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.
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.
Poor-quality chrome plating can cause numerous difficulties, so effective hard chrome plating troubleshooting is essential. In the guide below, we'll break down 10 common chrome plating problems and discuss the adverse effects they can have on your operations.
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.
20 Νοε 2018 · Hard chrome plating technique has been widely used to corrosion-resistant with a thickness of less than 100 μm without re-processing. However, hard chrome coating always generates the tensile residual stress and microcracks. They reduce the fatigue strength of the machine parts.
19 Απρ 2008 · Rotating bending fatigue test results indicate better performance for the conventional hard chromium plating in relation to the accelerated hard chromium electroplating.
