Abstract:

The nickel-based matrix material provides the perfect combination of hard filling coatings, hardness, resistance to coating and corrosion produced with homogeneously dispersed tungsten carbon (WC) particles. In this study, the production of hard-filled coating was carried out by adding global toilet particles to the plasma arc source and nickel-based matrix material, and the impact on the exhaust amount of the exhaust environment was studied. The overall hardness of the cover is measured by the macro Vickers (HV10) method. In addition, the hardness of the toilet particles and the matrix/carb wheat is determined by HV3 method. The "ball-on-disc" coating tests of the coating were performed in both dry and weight 5 % NaCl water solution, under 10 N load and at room temperature. As the opposite element, the diameter of 6 mm aluminum ball was used. The sliding speed and distance are adjusted to 3 cm/s and 2000 m respectively. The topography of the stretching trace is extracted with a profile meter every 500 meters and the volume material loss is calculated. The loss of material has increased with the increased sliding distance. The volume material loss in the naCl solution environment was found to be higher than the dry environment. In the coating test in the NaCl solution, it was found that material loss occurred not only due to the mechanical effect of coating but also due to corrosion.
