In this research, cream-tungsten carbide nano composite coating was produced by electroplating method. In this section, the equipment used in this research, the materials used along with the test design and the parameters studied in it are mentioned. The highest abrasion rate is obtained at the lowest amount of coating hardness, ie at a frequency of ۱ Hz, and the best abrasion resistance at a higher hardness coating, ie at a frequency of ۱۰۰۰ Hz. As can be seen in this diagram, the abrasion resistance of coatings at high frequencies has not improved much despite the presence of particles in these coatings, which can be due to the presence of more agglomerate particles in these coatings. Be. By increasing the frequency from ۱ to ۱۰۰۰ Hz, the hardness of the coating increases from HV ۵۹۰ to HV ۷۰۵, which is due to the presence of more particles in the coating at high frequencies. Coating hardness increases with increasing presence of particles in the coating and decreases with decreasing presence of particles in the coating.
