HVOF thermal spraying: An alternative to hard chrome plating
- Sulzer Metco, Westbury, NY (United States)
In recent years pressure to find alternatives to chromium electroplating has accelerated dramatically. While it is not likely that the process will be banned completely, the trend points to severe limitations. Industries must now look closely at their applications, and actively consider alternatives to hard chrome plaint. One of the most viable alternatives in thermal spraying. Recent advances in high-velocity oxygen fuel (HVOF) technology offer an environmentally safer, cleaner and less-expensive alternative to chromium plating. It has been shown here that HVOF coatings can be used as chromium plating alternatives for many different applications. The HVOF process offers several advantages over chromium plaint including thicker coating capability, no part size restrictions and no hazardous waste products. A number of HVOF coatings have had excellent results in laboratory and field testing, and can be considered as effective replacements for hard chrome. The choice for a suitable replacement can only be made after careful assessment of the conditions associated with the application in question.
