The Effect of Melting Current on the Microstructure and Properties of Iron-based TiC Wear-resistant Layer
In order to study the effect of plasma cladding current on the microstructure and properties of iron-based TiC wear-resistant layers,iron-based TiC wear-resistant layers with cladding currents of 140 A,160 A,180 A,and 200 A were prepared,and their microstructure,microhardness,and abrasive wear performance were characterized and analyzed.The results show that the microhardness of the wear-resistant layer first increases and then decreases,while the weight loss from wear shows a gradually increasing trend.When the melting current is 140 A,the wear resistance of the wear-resistant layer is the best,with a microhardness HV of 755,which can achieve good comprehensive performance.
