Abstract
A method is provided for treating a metal working tool element made of cemented carbide materials, as hereinafter described, comprising the operation of implanting into a working surface of the tool element ions of a material such as to modify the implanted region of the working surface of the tool element in such a way as to prevent adhesion between the matrix metal of the cemented carbide tool element and a metal being worked by the tool element. Metal working tool elements so treated are also disclosed.
Claims19
A method of treating a metal working tool element made of cemented carbide materials, as hereinbefore described, comprising the operation of implanting into a working surface of the tool element ions of a material such as to interact with the matrix metal of the tool element in such a way as substantially to prevent adhesion between the matrix metal of the cemented carbide tool element and a metal being worked by the tool element.
A method of treating metal working dies made of cemented tungsten carbide comprising the operation of implanting into a working surface of the dies ions of a material such as to interact with the matrix metal of the dies in such a way as substantially to prevent adhesion between the matrix metal of the cemented tungsten carbide and metal being formed by the die.
A cemented carbide, as hereinbefore described, metal-working tool element having a working surface into which has been implanted ions of a material such as to interact with the matrix metal of the cemented carbide tool element in such a way as substantially to prevent adhesion between the matrix metal of the cemented carbide tool element and a metal being worked by the tool element.
