The present invention relates to a method for coating ceramic material, and more particularly the coating of ceramic material with silicone coatings having zirconate coupling agents therein or with a silane coating having a silicone coating applied thereon. Ceramic material is cleaned 26 with a suitable cleaning agent to remove undesired oils or other matter, such as particulates, is heated 28 to dry excess moisture from the surface of the material, and is coated 30 with a silicone coating, preferably having an effective amount of zirconate coupling agent therein 24, prior to the coating being cured 34 at temperature of from about 400-F to about 525-F for a period of between about 20 minutes and one hour. The resulting coated ceramic material has superior abrasion resistance, heat resistance, high hardness, and low co-efficient of friction. The present method of coating ceramic material and the coated ceramic material itself finds particular application in the production of buttons for articles of clothing. One aspect of the invention relates to a button that has improved strength and durability characteristics, such button preferably comprising stabilized zirconia, alumina, zirconia-alumina composites, or silicon carbide wisker reinforced ceramics. |
