Abstract

Material coating is a technology that is used in a variety of materials, and thanks to this adjustment, we improve the surface properties. It increases corrosion resistance, wears resistance, improves a functional quality and changes or improves aesthetic design. Increased demands are placed not only on productivity but also on the quality of finished products. The paper deals with galvanic plating. The work experimentally evaluates the occurrence of defects when is comparing the technology of mass and suspension plating. The research focused on the progress and evaluation of the results obtained in the experiment. There were performed the control measurements of coating thicknesses, was controlled the correct ratio of elements of the alloy used for electroplating and visual inspection of defects in products.The results of the work should contribute to the comparison of the technology of drum and hinge method of galvanic coating with ZnNi alloy. The aim of the thesis is to compare possible defects and propose measures for their removal. The correct coating thickness does not only increase the life of the product, but also has a significant impact on the quality of the final parts.
