Markable achievements 

Ÿ Group 1: surface coating and technology of lightweight alloys

        Based on the project supported by the Chinese Academy of Sciences Western Light (No. Y32Z010F10), a new functional composite films system with high load-bearing, self-lubricant and anti-corrosion properties is developed to solve the wear-corrosion synergy failure existing in the current magnesium alloy parts (Fig.1), and Al/AlN/CrAlN/CrN/MoS2 gradient duplex coating is synthesized on magnesium alloy (Fig.2). The results show that the hardness of uncoated magnesium alloy has increased by 20 times (Fig.3). The gradient duplex coating has the good self-lubricating and anti-corrosion properties, and its wear rate and corrosion rate was only 1/140 and 1/136 compared to that of the uncoated magnesium alloy, respectively (Fig.4 and 5). In addition, a serious corrosion degradation with a great amount of corrosion products and cracks can be observed on the surface of uncoated sample, whereas little corrosion products can be seen on the surface of coated sample, hinting the better chemical stability (Fig.6). The study appears in Vacuum（2014，101:171-176）.

Ÿ Group 2-- Self-lubrication and Wear-resistant muli-functional Coating Technology for Equipments:

  The researchers have developed series of multi-functional coating materials with self-lubricating wear-resistant, impact-resistant, high load-bearing, adhesion-resistant properties to solve equipment industrial technical problems, The research achievement enhanced market competitiveness significantly.By Sep. 2013, the research center had provided free service and technical support for more than 60 companies in various fields such as heavy equipment, weapon, textile industry. Over 70 batches of the coated samples had passed approval test and 3 of them had been converted to products: friction-reduction coating for industrial printer frame (figure 7), self-lubrication and wear-resistant coating for piston (figure 8) and wear-resistant and protective coating for axises/piston column (figure 9).

Ÿ Bionic self-cleaning super-hydrophobic coating technology:

    A novel bionic self-cleaning superhydrophobic polymer functional coating with MNBS structure by conventional attempts was successfully fabricated on the surface of some substrates (such as aluminum, copper, steel and glass) by one-step casting process. It revealed excellent drag and noise reduction, self-clean and anti-ice/snow performance in the applications of underwater crafts and transmission lines (Figure 10). The coatings possess excellent engineering application properties such as long-term stability, high cohesive strength, anti-temperature change and chemical-media resistance (Figure 11). The research has been published in related journal publications such as Advanced Materials. The research achievement has been applied for five national patents (three granted). At present, the research team is cooperating with national power company to develop  “the self-cleaning glass insulators ”，and promoting the engineering applications and industrialization (Figure 12).
