The present invention is to introduce a tungsten carbide - steel gradient resistant materials.
Resistant materials can form gradients infiltrated tungsten carbide into steel (WC) by high-energy ions.
Currently on the market of high-chromium steels, cast stone and other wear-resistant surfacing materials present WC short life, the shortcomings of hardness, strength, toughness.
The invention form WC on the carbon or alloy steel surface on discharge principle. WC hardened layer ≥ 0.8mm, which WC rich layer over 0.3mm. WC - steel wear resistant materials gradient performance is usually hardened alloy tool steel 4 to 15 times, and has integrated high performance hard, high strength, high toughness, etc., which meets the technical requirements of many anti-wear conditions.
