| ENDURAKOTE® Plating (continued) _Q a \— c o u (!) I C. Adhesion c ENDURAKOTE® plating will not flake, crack, chip, peel or 0 otherwise separate from the base material under standard bend * tests or under conditions where severe heat is induced. The 5 adherence is adequate to withstand the extremely high compressive stresses in the contact areas ofball and industrial roller bearings. D. Effect On Base The purity of the chromium surface will not be less than 99% as deposited. A comprehensive testing program at KAYDON established that bearings with ENDURAKOTE® plating exhibited load carrying capacities and life expectancy equal to or better than uncoated AISI 52100 steel bearings. E. Corrosion Resistance ENDURAKOTE® plating resists attack by most organic and inorganic compounds with a pH within the range of 4 and 11, except sulfuric and hydrochloric acids. Porosity of the base metal, compound concentration and exposure time to the compound become corrosion factors, but ENDURAKOTE® plating greatly enhances the base material. In severe salt spray tests as well as tap water immersion tests, AISI 52100 steel with ENDURAKOTE® plating proved equal to fully hardened AISI 440C stainless steel in resistance to rusting. In many instances, ENDURAKOTE® plating is better for corrosion protection than cadmium plate, zinc plate, phosphates, chromates, black oxide or normal chrome plate. We invite inquiries about and will be pleased to arrange tests to qualify ENDURAKOTE® plating for specific environments. |
