No grinding of excess plating is permitted in this type of coating. A successful process is determined by the same test methods common to standard hard chromium coatings, i.e., visual, thickness, adhesion, ferroxyl and embrittlement testing.
Abusive grinding AP can cause macro-cracking in an otherwise good chrome deposit.Hard chrome must be ground using the proper wheel, plenty of coolant and with very slow feed rate. If hard chrome is ground without these precautions the chrome will overheat and the occluded hydrogen will expand causing the macro-cracking.
hexavalent chromium, exist in several forms known as chromates. Close to a half million welders of stainless steel will be affected by this standard, although chromates can also be present in varied industries involving photo-graphic pigments, dyes, surface coatings, paints, inks, plastics, thermal cutting and chrome plating.
Jan 02, 2014 Welding fumes can have a lot of bad actors. Often the effects manifest themselves as metal fume fever . Hex chrome and nickel carbonyl from SS welding.
