Abstract
New and improved structures in tools subject to wear and attrition when engaging or engaged by work or material being worked on thereby. Synthetic diamond material is formed in situ on a select portion or portions of the surface of a hard substrate or tool support to define or cover the portion of the tool substrate adjacent the work operated on by the tool in a manner to provide a hard wear resistant work engaging surface or surfaces which offers substantially greater resistance to abrasion and frictional deterioration than the material of the substrate or tool base. In one form, the synthetic diamond material is formed on and welded to the surface of the substrate in a single operation involving the application of intense radiant energy beamed against particles of carbon which are converted to a solid synthetic diamond structure of defined shape directly against the solid substrate. In a particular form, the synthetic diamond material is formed with a cutting edge for the tool having substantially the hardness and wear resistance of diamond.
