Effect of Electrical Contact Strengthening on Microstructure and Properties of Flame-sprayed Ni60-WC Coating and 40Cr Substrate AITranslate
Abstract AITranslate
Nickel-based tungsten carbide（Ni60-WC）was coated on 40 Cr substrate by oxygen-acetylene flame spraying,and then the coating was subjected to electrical contact strengthening.Microstructure of coating section was observed by metallographic microscope before and after electrical contact strengthening,microhardness distribution of coating section was analyzed by microhardness tester,and tungsten element distribution of coating and substrate was analyzed by SEM surface scan.The results indicate that electrical contact strengthening can significantly improve the coating quality and hardness,and result in metallurgical bonding between coating and substrate.
