摘要： A method for forming a ceramic coating on a substrate comprises immersing the substrate such as stainless steel in an aqueous solution containing a silicic acid compound such as sodium silicate and/or a metal salt of oxygen acid such as an aluminate, and irradiating the substrate with a laser beam. By this method, a dense and fine ceramic coating can be uniformly formed on the substrate without using an apparatus of large scale required in the gas phase method and without heating the system to a high temperature.

摘要： A method for forming a ceramics film on the surface of a substrate comprises performing spark discharge in an electrolytic bath, wherein the electrolytic bath comprises an aqueous solution of a water-soluble or colloidal silicate and/or an oxyacid salt to which ceramics fine particles and/or specific fine particles are dispersed and the spark discharge is carried out in the electrolytic bath while ensuring the suspended state of the ceramics particles and/or the specific fine particles in the electrolytic bath. The method makes it possible to effectively form, on the surface of a metal substrate, ceramics films having a variety of color tones as well as excellent insulating properties and hardness. Moreover, it further makes it possible to effectively form a composite ceramics film having excellent wear resistance on the surface of a metal substrate.
