The corrosion and tribocorrosion behaviors of Type 304 stainless steel coated by two different amorphous carbon films, including undoped and Cr-doped amorphous carbon films, were investigated in HNO3 solution, and bare Type 304 stainless steel was used for comparison. In static-corrosion environment, the corrosion current densities of the carbon-based films were decreased by 41% to 97%, when compared with stainless steel, thus suggesting that the corrosion protection properties of the films were excellent. Tribocorrosion tests were conducted to synchronously monitor the open-circuit potential and friction coefficient of the films, and the friction coefficient increased with the increase of HNO3 concentration. Therefore, the carbon-based films could effectively improve the wear resistance of Type 304 stainless steel in HNO3 solutions.

Shape Memory Materials

Using laser cladding method, the coating of Fe-Mn-Si shape memory materials (SMM) was prepared on the surface of AISI 304 stainless steel. The microstructure and microhardness of SMM laser cladding coating were measured by using a metallographic microscope and a scanning electron microscope, respectively. The phase composition was determined by X-ray diffraction. The wear resistance was evaluated on a high speed reciprocating friction tester. The results show that microhardness of the SMM coating is about Hv263, higher than that of the substrate (Hv225); the SMM coating is composed of ε-martensite and γ-austenite phases; the average friction coefficient of the substrate and SMM coating is about 0.85 and 0.71; the SMM laser cladding coating is of excellent wear resistance validated by friction coefficient, worn-out appearance and wear loss.
