Effect of Rare Earths on Microstructure and Wear Resistance of Electrodeposition Ni-based Metal Composite Coatings陈蓉娜摘 要:Ni/Al2O3 composite coating was prepared by double pulse electrodeposit technique, and microstructure and wear resistance of Ni/Al2O3 composite coating were studied by SEM, TEM and property test. The results show that the distribution......
China) 摘要:Mo-base materials have special use in many fields. One of them is to use as substrate materials for dynamic airproof ring. But the hardness and the wear resistance of Mo-base materials are not good for working under the condition of high temperature and high speed. So it must be cover with chromium coating that has high hardness, excellent wear resistance and high credibility. At present......
