Wear and texture coatings for components used in manufacturing glass light bulbs
View Patent ↗The present disclosure relates to a quench mold that may include an interior cavity and a coating on the interior cavity. The coating may include a plurality of particles such as metal-coated particles.
1. A quench mold, comprising:
a component having an interior cavity; and
a coating on a surface of the interior cavity of the component, wherein the coating comprises a plurality of metal-coated particles, wherein the metal-coated particles further comprise a coating of a superabrasive material and wherein the metal-coated particles having the coating of the superabrasive material have a porous open-structure.
2. The quench mold of claim 1 , wherein the coating on a surface of the interior cavity of the component further comprises a metal matrix.
3. The quench mold of claim 1 , wherein the metal-coated particles comprise a metallic coating of titanium, chromium, nickel, cobalt, copper, tantalum, iron, silver or combinations or multiple layers thereof.
4. The quench mold of claim 1 , wherein the metal-coated particles comprise graphite particles.
5. The quench mold of claim 1 , wherein the coating on the interior cavity retains a volume of water having a volume that is about 0.4 mm 3 to about 0.9 mm 3 per cubic millimeter of the coating.
6. The quench mold of claim 3 , wherein the metal-coated particles comprise graphite and the metallic coating comprises copper or nickel.
7. The quench mold of claim 2 , whereby the metal matrix comprises nickel, chrome, copper, cobalt, or alloys thereof.
8. The quench mold of claim 1 , whereby the coating on the surface of the interior cavity of the component has an overall thickness of about 50 to about 500 microns.
9. The quench mold of claim 1 , whereby the metal-coated particles comprise one or more of graphite, hexagonal boron nitride, talc, and MoS 2 .
10. The quench mold of claim 1 , wherein the superabrasive material comprises cubic boron nitride particles.
11. The quench mold of claim 1 , wherein the additional coating of a superabrasive material has a thickness of about 1 μm to about 25 μm.
12. The quench mold of claim 3 , wherein the metallic coating comprises about 60 weight % to about 80 weight % of the metal-coated particles.
13. The quench mold of claim 3 , wherein the metallic coating has a thickness of about 200 microns to about 500 microns.
