Abstract

Electrodeposition of wear-resistant compositions on the surfaces of parts makes it possible to increase the reliability and durability of machines. Studies have been carried out on the process of applying Fe-WC composite galvanic coatings (CGC) from a suspension electrolyte containing 550–600 g/L FeCl₂·H₂O and microabrasive tungsten carbide powder. A high incorporation of dispersed phase particles into the coating was obtained. The properties of Fe-WC composite coatings were studied. A relationship has been established between the concentration of tungsten carbide particles in the electrolyte and the current efficiency of the composition as well as the WC content in the coating. Some physical and mechanical properties of CGC have been determined without their mechanical pretreatment, in particular, microhardness and wear resistance. The roughness of Fe-WC compositions was studied in comparison with Fe–Al₂O₃ coatings.

碳化钨对Fe-WC复合电镀层沉积工艺及性能的影响

在零件表面电沉积耐磨成分可以提高机器的可靠性和耐用性。我们对使用含 550-600 g/L FeCl2-H2O 和微研磨碳化钨粉末的悬浮电解液涂覆铁-碳复合电镀涂层 (CGC) 的工艺进行了研究。涂层中分散相颗粒的含量很高。研究了铁-碳化钨复合涂层的性能。在电解液中碳化钨颗粒的浓度与组合物的电流效率以及涂层中的碳化钨含量之间建立了关系。在未进行机械预处理的情况下，测定了 CGC 的一些物理和机械性能，特别是显微硬度和耐磨性。与 Fe-Al2O3 涂层相比，对 Fe-WC 成分的粗糙度进行了研究。
