Method of coating cutting edges
View Patent ↗A process for applying a coating containing a fusible material to a cutting edge of a cutting tool includes heating the fusible material to fuse the same, the heating being provided by microwave energy.
1. A process for applying a coating to a cutting edge of a cutting tool which comprises applying a dispersion or suspension of a fusible material to the cutting edge and heating the fusible material employing a source of microwave energy so as to fuse the fusible material into a substantially uniform coating which adheres to the cutting edge.
2. The process of claim 1 wherein the cutting edge is fabricated from metal.
3. The process of claim 1 wherein the cutting edge is fabricated from ceramic or glass.
4. The process of claim 1 wherein the fusible material is a halogenated polymer.
5. The process of claim 1 wherein the fusible material is a low molecular weight halogenated polymer.
6. The process of claim 1 wherein the fusible material is heated to a temperature of from about 300 to 390° C. for a period of from about 1 to about 60 seconds.
7. The process of claim 1 wherein the fusible material is heated to a temperature of from about 310 to about 360° C. for a period of from about 5 to about 15 seconds.
8. The process of claim 1 wherein the source of microwave energy is a gyrotron providing power densities of up to about 10,000 KW per square inch.
