A metalloceramic NiCrBSiFe−WC coating on structural steel 40Kh was prepared by the method of laser cladding. The cladding was performed using a multichannel continuous СО 2 laser radiation using the complex of ALTKU3 model produced by LLC "Centre of laser technologies", the city of Vladimir. The complex includes a multichannel (40 rays) СО 2 laser with the output power of 3 kW and a technological stand with five coordinates for ray manipulation and with two ones for manipulation of the piece under processing. The prepared samples were examined metallographically. It is shown that at optimal modes a practically pore-free coating is formed with a minimal penetration into the base ensuring metallurgical fusion. According to the X-ray spectral microanalysis data the chemical composition is practically the same as that of the raw powder. In particular, the content of iron in the granules and in the matrix is nearly the same (about 4…5 %). Due to the automatization of the processing by crossed rollers the sample surface after cladding is nearly flat and only requires a slight machining. The thickness of the cladding layer is about 700 μm in one pass. No cracks in the plane of the sample were observed. The weld junction demonstrates the same structure lengthwise thus indicating a high uniformity of the heat input during the cladding. The size of the thermal effect zone in the substrate is about 450 μm. The laser cladding of the highly alloyed powder of the system NiCrBSiFe−WC onto the structural steel by means of the multichannel СО 2 laser makes it possible to obtain a high-quality wear-proof coating since, in contrast to single ray lasers, it provides a high uniformity of integral heat input in the processing zone.
