| Abstract: | A scanning electron spectroscope and a microhardness indentation tester were used to study the microstructure and mechanical properties of plasma sprayed NiCrBSi coatings before and after laser remelting,and the sliding wear behavior of the coatings was investigated.It was found that defects like pores,cracks and unmelted particles were eliminated by laser remelting,resulting in increased density and hardness of the coating.The laser remelted coating had metallurgical bonding,and was twice the anti-wear abi... |
