ABSTRACT:
Parts for an internal combustion engine such as a piston and a cylinder head manufactured by mixing inorganic coating material with potassium titanate fibers, silicon nitride whiskers and/or glass balloons, adding to and mixing with the above mixture calcium oxide (CaO) as a hardening promoter, drying the article so produced, and baking the same. The potassium titanate fibers is 5 to 40%, the silicon nitride whisker is 10 to 50%, and the glass balloon is 0 to 15% in weight of the inorganic coating material, and the calcium oxide is 1 to 10% of the total weight of the potassium titanate fibers, silicon nitride whiskers and/or glass balloons. The drying time is reduced by adding CaO as a hardening promoter.
