Morphology and phase composition of MAO ceramic coating containing Cu on Ti6Al4V alloySi-Rong Yu,Qiang Yao,Hong-Chao ChuCollege of Mechanical and Electrical Engineering, China University of Petroleum (Huadong)摘 要:A ceramic coating containing Cu element was prepared on Ti6Al4V alloy using micro-arc oxidation(MAO)technology.After copper ions were added......
and wear tester. The microhardness and thickness of the oxide coatings were measured. The results show that the ceramic coating is mainly composed of α-Al2O3 and γ-Al2O3. During oxidation, the temperature in the microarc discharge channel is very high to make the local coating molten. From the surface to interior of the coating, microhardness increases gradually. The microhardness of the ceramic coating......
, distribution of elements and microhardness of α-case layer. The α-case layer thickness of Ti-1100 casting with ZrO2 primary coating is approximately 38 μm, which is higher than that with Y2O3 primary coating (18 μm). Ti-1100 casting using ZrO2 primary coating shows higher surface microhardness than that using Y2O3 primary coating. The higher mold temperature results in more severe interfacial......
