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.
This research has investigated the development of surface crack of hard chrome through the variations of chromic acid concentration, catalyst content and plating temperature, and...
19 Απρ 2008 · In this paper a simple image analysis procedure to determine microcrack density is presented in order to demonstrate it as a fundamental tool to estimate the fatigue, corrosion and wear behavior,...
27 Σεπ 2018 · Analysis of the Base Material and Hard Chrome Plated Layer in an Unloaded State. September 2018. MANUFACTURING TECHNOLOGY 18 (4):616-620. DOI: 10.21062/ujep/148.2018/a/1213-2489/MT/18/4/616....
25 Φεβ 2023 · Hard chrome plating is a widespread coating technique for applying a protective coating layer to the surface of components. Due to the simplicity of industry-applied lead anodes, components with complex geometry are often plated with a non-uniform layer of chrome.
23 Ιουν 2020 · A micro-cracked hard chrome with the thickness range of 5–15 µm was deposited on the Al layer by the electroplating process. The micro-cracked hard chrome layer was considered as a model material to investigate the deformation processing of the metal laminate with a discontinuous interlayer.
