In recent times we have seen a push away from conventional hard chrome plating methods with a demand for a more environmentally friendly process. The High Velocity Oxygen Fuel (HVOF), High Velocity Air Fuel (HVAF) and Laser processes all provide viable alternatives to traditional hard chrome plating. These Metal Spray and Laser processes enable harder, more wear resistant coatings with increased corrosion resistance to that of traditional methods, all while being more environmentally friendly with the removal of the need for hexavalent chromium. HVOF uses oxygen and a fuel source, HVAF uses air (compressor) and fuel, and the Laser Cladding process uses a laser beam to deposit the coatings. No solvents or chemicals are used, just pure metal.
The toxic effects of exposure to hexavalent chromium used in traditional hard chrome plating methods can result in cancer, organ damage, brain damage and lung/kidney failure. Hexavalent chromium by-products emitted during operations are man-made and hazardous to the environment. These toxicological effects are the reason companies around the world are seeking alternate, safer methods.
