Scientific Research Achievements of School of Materials Science and Engineering, Changchun University of Technology
A prominent feature of the college is that it has more advanced modern experimental equipment at home and abroad. The laboratory covers an area of nearly 2,800 square meters, with complete equipment for material analysis, performance testing and materials. The laboratory is divided into material microscopic detection and analysis laboratory, metallographic laboratory, high-frequency laboratory, metal anticorrosion and protection laboratory, mechanical performance laboratory, polymer material laboratory, heat treatment laboratory, chemical analysis laboratory, nondestructive testing laboratory and domestic first-class welding experiment teaching base. Advanced materials testing instruments and equipment at home and abroad mainly include transmission electron microscope (JEM-2000EX), scanning electron microscope (JSM-5500LV), energy spectrometer (FOCAU2 of American EDAX company), X-ray diffractometer (D-MAX IIA of Japan), direct reading spectrometer (PDA-7000 of Shimadzu of Japan) and electro-hydraulic servo dynamic and static fatigue tester. Electronic universal tensile and compressive testing machine, ceramic cathode ion coating machine (MH-800), X-ray flaw detector, optical microscope for metallographic quantitative analysis, optical microscope (MM-6, Germany), ion sputtering instrument (KYKYSBC- 12), coating machine (JEE-4X, Japan), ion thinning instrument (GL-). Metal surface anticorrosion equipment, vacuum melting furnace, vacuum sintering furnace, ultra-thin slicer (Leica Company), various wear testing machines, various heat treatment test equipment, various advanced welding equipment, Fourier transform infrared spectrometer (Niccoli, USA), laser particle sizer (USA), discharge plasma sintering machine (Japan), vibrating sample magnetometer (lakeshore, USA) and mettler precision densimeter (Switzerland).

In the teaching work, the college pays attention to the teaching mode of combining basic theory learning with experimental operation and production application, and attaches importance to undergraduate experimental teaching. General laboratories and experimental instruments are open all day, without any restrictions, and the experimental class hours of modern large-scale instruments for each undergraduate are required to exceed 15 hours (compulsory experimental class hours include transmission electron microscope, scanning electron microscope, energy spectrometer, X-ray diffractometer, electro-hydraulic servo fatigue tester, direct reading spectrometer, etc.). ), especially during the graduation thesis. This is difficult for other universities in China to do.

The welding laboratory can provide welding tests for 70 students at the same time, equipped with various advanced welding equipment, and the use of consumable materials such as welding wires is basically unrestricted.

This shows that the goal of cultivating students in the college requires students to have excellent practical ability in addition to professional theoretical knowledge. Emphasis is placed on heuristic interactive teaching methods and the cultivation of students' ability to analyze and solve problems independently, vivid multimedia teaching and the cultivation of students' innovative ability. Encourage students to participate in teachers' research groups, improve students' awareness of integrating theory with practice, and improve students' practical ability. Encourage students to go deep into factories and mines to carry out professional research and participate in technical research activities, and encourage students to carry out professional technological innovation and invention-creation activities. It has formed a three-dimensional learning atmosphere from classroom to society, from experimental skills to engineering application. The trained students can basically understand theory, experiment and application, and become useful talents in society after graduation. College graduates have a high rate of postgraduate entrance examination, the employment rate is over 95%, and the employment satisfaction rate is over 80%.

In addition to paying attention to students' professional study, the college also attaches great importance to students' ideological and political education and organizes various colorful extracurricular activities. Adhere to the educational concept of "to learn higher cultural knowledge, we must first learn to be a noble person". Make students consciously strengthen moral cultivation, have a deep sense of honor and disgrace, and strictly demand themselves according to the code of conduct of college students, thus creating a strong learning atmosphere and cultivating the cohesive spirit of honesty, friendship, unity and cooperation.

As an important part of going deep into the army, rural areas, communities and factories, college students' summer social practice activities in the countryside have been rated as "excellent teams" of social practice at the provincial and municipal levels for many years in a row, and won the title of "advanced collective in the 20th anniversary of Changchun University of Technology".

Relying on the "Challenge Cup" extracurricular scientific and technological works competition for college students, the college actively enhances students' innovative consciousness and improves their practical ability. Won the third prize, provincial special prize, first prize, second prize and third prize of the 8th National Challenge Cup in the extracurricular scientific and technological works competition for college students. Through the activities, students' interest in professional learning has been greatly improved, and the construction of academic atmosphere in the college has also been promoted.

In recent years, the college has made great progress in scientific research, and has established school-level research institutes (research centers) such as material technology and equipment engineering, welding materials and technology, material surface engineering technology, polymer synthesis and application. The college has carried out extensive industry cooperation with foreign countries and established a "metal material processing engineering research and development base" in Tonghua Iron and Steel Group; In Jilin Ferroalloy Co., Ltd., the "R&D base of alloy material technology and energy-saving engineering" was established; In Siping Gaosida Nano Manufacturing Equipment Co., Ltd., the "Research and Development Base for Manufacturing Technology and Application of Metal Nanomaterials" was established. We have also established various forms of cooperative relations with large enterprises in Beijing and other places, Tsinghua University, Institute of Metals of Chinese Academy of Sciences, Key Laboratory of Automotive Materials of Jilin University, tokyo institute of technology, Northeastern University, China FAW Group, Jihua Company, Changke Group, Tonghua Group, Jilin Oilfield Company, Angang and Zhejiang.

The college has an active academic atmosphere and fruitful scientific research results. More than 200 scientific papers have been published in recent three years, and more than 50 papers have been retrieved by SCI, EI and ISTP. Undertake more than 40 national, provincial and ministerial scientific research projects, with an average annual research funding of more than 4 million yuan; He won 8 provincial and ministerial scientific and technological achievement awards and 2 invention patents 12, and the promotion of the achievements created economic benefits for the society of about 90 million yuan. Among them, "low-carbon and low-alloy air-cooled bainite steel" has been successfully used in truck front axle, and its fatigue life has reached and exceeded the index of similar products in Japan; The project of "Localization of Jetta Car Connecting Rod" adopts non-quenched and tempered treatment process instead of quenched and tempered steel, which improves production efficiency and reduces production cost. Isothermal normalizing process and production line of alloy carburized billet have passed the appraisal of national achievements and been approved as national key new products. The localization of IF steel plate for automobile deep drawing parts has created good economic benefits in the aspect of light weight of automobile steel plate. The "laser cladding technology" modified the surface of the material, which created a direct benefit of over120,000 yuan for FAW Group. In addition, a lot of achievements have been made in the preparation and application of wear-resistant materials for mining machinery, aluminum, magnesium, titanium alloys, metal composite ceramics, functional alloy materials, nano-materials and plasma spraying surfacing composite materials.
