Abstract

In order to investigate the tribological performance of laser clad coatings on die steel, laser cladding techniques were adopted with Fe-based alloy powders. The wear tests were carried out by using laser clad layers as low samples and GCr15 steel ball as upper samples with HT-500 wear tester. The morphologies of wear scars were observed with optical microscopy, and the wear width and the depth of the wear samples were measured. In the meantime, the wear rate was calculated theoretically. Under dry sliding condition, As the tests show, friction coefficient decreased with the load increase gradually, then increased. And the wear performance of 300g load was better than that of 500g load under dry sliding condition. Under lubricant condition, with the increase of load, the friction coefficient decreased gradually. And the friction coefficient, wear rate and wear width under lubricant are smaller than that under dry friction with the same load.
