Abstract
An ion plating method and product therefrom wherein ions of a metal are implanted into or/and plated onto a substrate to increase the hardness of the surface. After plating, the product can be reacted with carbon, boron, nitrogen or another metal, thereby forming the carbide, boride, nitride or metal compound of the plating metal coating. Hardening of the product by quenching follows which produces a cutting tool of superior qualities.
Claims6
A coated metal product comprising, a steel martensitic substrate, a metal selected from the group consisting of:
- scandium, titanium, zirconium, hafnium, vanadium, columbium, tantalum, chromium, molybdenum, tungsten, lanthanum, cesium, praseodymium, neodymium, promethium, samarium europium, gadolinium, terbium, holmium, dysprosium, erbium, thulium, yttrium, ytterbium, lutetium, actinium, thorium, protactinium, uranium, neptunium, plutonium, americium, curium, berkelium, californium, einsteinium, fermium, mendelevium, nobelium, lawrencium, iron, cobalt, nickel and boron imbedded by ion bombardment into the surface area of said steel substrate, and a metal salt selected from the group consisting of a carbide, boride and nitride of said selected metal, bonded to the outer surface of said selected metal.
A coated metal product comprising:
- a. a martensitic iron substrate;
- b. an implanted subsurface along the surface of said substrate, said subsurface containing an element which is insoluble in said substrate;
- and
- c. a coating along said subsurface of a coating metal and a hardening substance reacted with said coating metal, said substance creating with said coating metal, a layer which is harder than the coating metal, itself.
