Description
A promising, alternative surface treatment to traditional case carburizing was recently developed by the Swagelok Company of Solon, Ohio. It enables extremely high ('colossal') super-saturation of carbon (up to 12 at%) to be achieved. Supported by physical metallurgy research at Case Western University, the colossal supersaturation treatment offers the advantage of hardening the surface while still retaining the corrosion resistance of stainless steel. Initial characterization included microindentation hardness, nano-scale hardness testing, and scratch hardness tests. Durability was determined using pin-on-disk tests, reciprocating pin-on-flat tests, and loop abrasion tests. The wear rates for treated and non-treated surfaces of Type 316 stainless steel specimens were quantitatively compared. Additional sliding friction and wear tests were performed in salt water. Results clearly indicate that the new carburizing treatment produces higher micro-indentation hardness, higher scratch resistance, and improved wear resistance in dry and salt water environments.
