7*24 all day longzhengzhou,china[email protected]The Process. Hard Chrome Plating, also known as engineering chrome, is a layer of chromium applied on metal parts through an electroplating process. The natural element chromium is used because of its characteristics to reduce friction, improve corrosion resistance, improve surface hardness and able to build thick deposits

Hard Chrome Surfaces: Adhesion, Masking, Grinding, Finishing. Although it is often said that the chromium layer will reproduce faithfully every defect in the base material, in actuality as the chrome deposit thickens it will level imperfections. For smooth as-is chrome plating, the basis material should be at least as smooth as the expected chrome

Jul 24, 2012 Cylindrical Grinding of Hard Chrome. Does anyone know a good place to find information on grinding hard chrome. I work in an industrial hard chrome plating shop, that has taken on grinding in the last 5 years. We grind all sizes of parts, plated in both heef and conventional chrome. We us a Norton grinder with 3 x 30 pink WRA-46-j8-v8 wheels

A. The microcracking is still present and effective after grinding. However caution should be taken when grinding the chrome plate as too large a cut or pressure can cause excessive heat and can induce cracking in the part from propagation of the microcracks. Certain types of grinding wheel should be used and extreme care taken

Chrome oxide (Cr2O3) is an inorganic compound of chromium and oxygen. It is one of the principal oxides of chromium and occurs naturally as the rare mineral eskolaite. Chromium oxide coatings (Cr2O3 coatings) impart many of the material’s favorable characteristics to coated substrates, including: Excellent Wear. Excellent Abrasion Resistance

For grinding balls, the last two ways are the best. Moreover, for super high chrome balls, air quenching is welcomed than oil quenching. But, like 10-18%Cr, oil quenching is the most popular. Quenching process: first heating the grinding balls up to the certain degrees in particular time, then quench directly to oil or air for several minutes
