A preparation method for an implant with a bionic anti-wear texture. The preparation method comprises the following steps: placing on a mobile platform of a femtosecond pulse laser processing system a titanium alloy to be processed, and performing femtosecond pulse laser processing according to a preset bionic texture diagram, so as to obtain an implant with a bionic anti-wear texture. In the preparation method, femtosecond pulse laser light is used to process textured patterns on the surface of a medical titanium alloy, so as to form a bionic texture, such that contamination from impurity ions can be reduced, and splashing and the generation of molten particles are reduced, thereby greatly improving the processing quality of a textured surface; moreover, an undulating bionic texture is designed on the surface of a material on the basis of bionic technology, such that the generation of particles during wearing can be reduced, and wearing particles are captured, thereby improving the stability of the titanium alloy during wearing, and thus reducing the extent of wearing on the surface of the material; and neither a secondary surface treatment after texturing nor other modification techniques are required, thereby improving the wear resistance of an implant.

Nickel-based coating composition for improving damping shock absorbing performance of cylinder head of diesel engine, method for producing the same and use thereof
3—NiCrBSi metal-based ceramic composite coating. The nickel-based barium titanate composite coating has an excellent damping shock absorbing performance and gives the substrate strength as well. Comparing with the conventional coating materials, the coating obtained by the present disclosure through plasma cladding technique not only bonds with the substrate in a metallurgic way, but also has a small heat affected zone, specifically, an excellent damping shock absorbing performance. In embodiments of the present disclosure, vibration and noise generated by the cylinder head is reduced 20% by using the shock absorbing cladding coating.

Smart coating and method for manufacturing the same
The present invention disclose a smart coating comprising a substrate, optionally a first insulating layer, a plurality of first sensing units, a second insulating layer, a plurality of second sensing units and optionally a wear-resistant layer, wherein the plurality of first sensing units and the plurality of second sensing units have piezoelectric effect. The smart coating can provide real-time monitoring and feedback of the worn state of the surface of a part while eliminating the need to adhere a senor. Compared with the existing sensors and substrates bound by adhesion, the smart coating provided in the present application can avoid poor adhesion between the sensor and substrate. Furthermore, damaged positions can be located precisely so as to provide more and more accurate information regarding worn state of the part surface, which is in favor of monitoring and post-stage analysis on the worn state of the surface of the part.
