Coated golf club head/component
View Patent ↗A golf club component, such as a golf club head and/or a golf club shaft, can comprise a golf club component substrate having an outer layer of titanium carbide, typically comprising at least forty percent (40%) carbon content. Alternatively, a golf club component can comprise a golf club component substrate, at least a portion of which is enveloped by a first coating layer of, for example, electroplated nickel, a second coating layer of, for example, electroplated chromium or palladium, and a third coating layer of titanium carbide applied by physical vapor deposition. The titanium carbide layer is durable and can provide the golf club component with a desired aesthetic appearance, such as a black color. Additionally, the golf club component can be coated with a fourth coating layer, such as a layer comprising a sealant or clear coat material.
1. A golf club component, comprising:
a golf club component substrate comprising iron, an iron alloy, titanium or a titanium alloy;
a first coating layer comprising nickel or a nickel alloy and having a layer thickness of from about 5 μm to about 30 μm;
a second coating layer comprising chromium or a chromium alloy and having a layer thickness of from about 1 μm to about 7 μm; and
a third coating layer comprising titanium carbide having a sufficient amount of carbon to provide a black appearance and having a layer thickness of from about 0.5 μm to about 1 μm, wherein the third coating layer comprises at least about forty percent (40%) carbon by weight.
2. The golf club component according to claim 1 , wherein the first coating layer has a thickness of from about 15 μm to about 25 μm.
3. The golf club component according to claim 1 , wherein the second coating layer has a thickness of from about 1 μm to about 3 μm.
4. The golf club component according to claim 1 , wherein the third coating layer comprises between about forty percent and seventy percent carbon by weight.
5. The golf club component according to claim 1 , wherein the total thickness of the first, second, and third coating layers is at least 16 μm.
6. The golf club component according to claim 1 , wherein at least two portions of the third coating layer have differing surface roughnesses such that the at least two portions have differing reflectivities, and wherein the at least two portions of the third coating layer comprise at least one matte portion and at least one glossy portion positioned to reduce glare for the user.
