- Common Chrome Plating Problems
In hard chrome electroplating, detecting defects is critical for addressing them before they cause structural unsoundness or breakdowns in industrial equipment. Poor-quality chrome plating can cause numerous difficulties, so effective hard chrome plating troubleshooting is essential.
15 Ιαν 2021 · Hard chromium plating is a traditional surface electroplating technology, which is a thick chromium coating on various substrate surfaces. Its thickness is generally more than 20 μm. The characteristics of chromium can be used to improve the hardness, wear resistance, mild corrosion resistance and other properties of the parts.
This information provides a basic overview of the most common hard chrome plating specifications including a breakdown of classes, appearance, finish, and types. For full details on each of these specifications, please visit SAE International, ASTM International, and Defense Standardization Program.
Hard chrome plating, also known as industrial chrome or engineered chrome, is used to reduce friction, improve durability, and extend the life of equipment. This type involves a much thicker layer of chromium applied to heavy-duty industrial parts.
One of the criteria is the thickness of the chrome layer, which must be from 0.3 mm to 0.4 mm. Another criterion is microhardness, which must be in the 900 - 1050 HV range. In terms of structure, the chrome layer must appear as a cohesive layer with a minimum amount of pores and cracks.
Hard chrome plating is an electroplating process in which chromium is deposited from a chromic acid solution. Thickness of hard chrome plating ranges from 2 to 250µm. Various types of hard chrome include micro-cracked chromium, micro-porous chromium, porous chromium and crack free chromium.
