  • Patent number: 6808802
    Abstract: This invention comprises a coating for equipment parts, particularly including chemical mechanical polishing equipment parts and other equipment that may experience wear or contaminant build-up. The coating includes a fluoropolymer based material that may also contain a colorant or pigment to visually contrast with particles or slurry that is deposited on the parts during use. In some embodiments, multiple layers are applied in contrasting colors so that when a layer closer to the surface begins to wear a lower layer will be readily visible, signaling that re-coating or replacement will soon be required.
