Abstract
Investigation of the technology of laser cladding of a titanium substrate and analysis of the properties of graded materials of Ti-Si and Ti-NiCr systems were carried out. Cladding was performed in Trumpf DMD 505 laser system of 5 kW power. A graded change in coating properties was determined by scanning electron microscope, optical microscope and X-ray diffraction. Analysis of hardness variations through thickness of the deposited layers was carried out by HV method. The possibility of providing sound graded coatings in order to improve the titanium substrate properties was proved.
