Abstract: Methods are provided of making annular, tungsten-carbide jewelry articles including finger rings, bracelets, earrings, body jewelry, and the like. Advantageously, the methods include providing a tungsten-carbide based annular jewelry article having a desired surface profile and including an annular band that includes providing a mixture of two or more powdered materials of at least 50 weight percent to about 90 weight percent tungsten carbide to form the annular band of the article into a pressure mold having a cavity of predetermined annular configuration and sized formed therein, the size of the mold being greater than the final size of the annular band, compressing the powdered material mixture at a pressure sufficient to form an annular blank, and sintering the annular blank at a temperature sufficient to form the tungsten-carbide based annular jewelry article so as to be long wearing and virtually indestructible during normal use thereof.

Medical, dental, and industrial devices or components are other examples. Method of manufacturing an article including a substrate comprising a first material and an inlay comprising a second material includes the steps of preheating the substrate; contacting a depression in a surface of the substrate with the second material; heating the second material at a point contact with the substrate causing it to liquify and flow into the depression; and moving the point of contact along the along the depression in the surface of the substrate while continuously feeding the second material and heating the second material at the point contact with the substrate to cause it to substantially fill the depression.
