Abstract
Product forming molds have surfaces conformally coated with a coating composite comprising superabrasive particles. In one embodiment, the mold surface is plated (electrolessly or electrolytically) or coated with a metal having superabrasive particles dispersed therein. In another embodiment, the composite is a SiC composite having superabrasive particles dispersed therein.
Claims20
An article comprising:
- a mold having a shaped surface;
- wherein one or more portions of the surface comprise a particulate superabrasive material in a matrix;
- wherein the superabrasive material comprises discrete superabrasive particles and wherein the matrix comprises a metal alloy;
- and
- wherein the mold surface is shaped and positioned to contact a material heated above a working point of the material during a molding process.
2 more elements
An article comprising:
- at least one mold surface that shapes molten material in a molding process;
- wherein the mold surface is coated with an adherent conformal coating comprising discrete superabrasive particles in a metal alloy matrix so that the coating contacts the molten material.
