Wear and Abrasion Resistant Coating - Hardide Coatings

Under abrasion testing (ASTM G65) the Hardide coating is up to four times more wear resistant than HVOF WC/Co (9%) – 50 microns of Hardide coating is equivalent to 200 microns of HVOF. It has a wear rate 40 times lower than abrasion resistant steel AR-500, 12 times lower than hard chrome and 500x better than Inconel 718.
