【発明の名称】耐摩耗性のダイヤモンド刃を有する工具、その製法並びにその使用

Document Type and Number:

Japanese Patent JPH06509844

Kind Code:

A

Abstract:

In order to improve the wear characteristics of tools with diamond cutting edges, it is proposed to coat the diamond body with a 0.5 to 6 mu m thick layer of at least one oxide of the metals zirconium and/or yttrium and/or magnesium and/or titanium and/or aluminum, preferably aluminum oxide. The coating is deposited from the gas phase at gas-phase temperatures up to 800 DEG C. Preferably the pulse-plasma CVD process is used for the coating. The diamond tools so coated are particularly suited for chip-forming machining of carbon-affinitive materials, such as iron-containing materials or steel.
