Electroplating deposits a metallic coating on a conductive surface using an electrolytic process. Zinc plating and silver plating are examples in YTSAB's treatment range.
How the coating forms
Metal ions in the process solution are reduced to metal on the component. Electrical conditions, solution chemistry, substrate and geometry influence the deposit. Preparation, rinsing and post-treatment belong to the overall process.
Geometry and local requirements
Edges, recesses and accessible flat areas do not necessarily have the same conditions for deposition. Mark the areas where thickness or another property must be verified. Requirements inside a hole or on a difficult-to-reach surface should be stated explicitly.
Different surface-treatment principles
Zinc electroplating and silver plating add metallic coatings. Anodizing forms an oxide layer from the aluminium surface. Processes such as phosphating and black oxidation change the surface through chemical conversion. They should not be treated as interchangeable process names.
A process name is only part of the specification
Provide the material grade, drawing revision, coating requirements, masking, appearance, quantity and inspection needs. Identify dimensions that apply after treatment. Two components carrying the same general finish description can still require different process and inspection arrangements.
From principle to an order
Use a defined trial when there are unresolved questions about a new component. Record the material and revision represented by the sample, the properties assessed and the responsible approver. See prototype and trial enquiries and thickness measurement.
