摘要：
The paper analyzed the effect of the laser treatment process on the properties of electrospark alloying coatings. The coatings were electrospark-alloyed using a VK20 electrode (80% WC and 20% Co) with a cross-section of 3 x 5 mm (the anod) onto samples made of carbon steel 45 (the cathode).Then, the coatings were treated with CO2 laser (continuous wave). The properties are assessed after laser treatment by analyzing the microstructure and measuring the microhardness. Distribution of elements in the electrospark alloying WC-Co coating with the subsequent laser treatment was done by micro-X-ray spectrum analysis (MRSA).
