    Abstract

    In order to investigate the tribological performance of laser clad coating on die steel, laser cladding techniques were adopted with Fe-based alloy powders. The tests were carried out by using laser clad layers as upper samples and GCr15 steel as low samples with HT-500 wear tester. The morphologies of wear scars were observed with optical microscopy, and the 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 shown, friction coefficient decreases with the load increasement gradually, and then increases. And the wear performance of 300 g load is better than that of 500 g load under dry sliding condition. Under lubricant condition, with the increasement of load, the friction coefficient decreases gradually. And the friction coefficient, wear rate and wear width under lubricant are smaller than those under dry friction with the same load.
