 treated by blasting, thermal energy is generated by change in the speed of the ejection powder before and after collision of the powder with the surface of the material to be treated, in the light of the energy conservation law. This energy conversion occurs only in deformed portions, with which the ejection powder collides. Thus, temperature rises locally in the ejection powder, the reactive ejecting gas and the vicinity of the surface of the material to be treated.
The rise in temperature is in proportion to the speed before the collision of the ejection powder. Therefore, if the ejection speed of the ejection powder is made high, temperature can be raised in the ejection powder, the reactive ejecting gas and the surface of the material to be treated. At this time, the ejection powder is heated on the surface of the material to be treated and consequently chemical reaction arises between elements in the ejection powder and the reactive ejecting gas, so as to produce a compound. Furthermore, the resultant compound is activation-adsorbed on the surface of the material to be treated by a rise in temperature of the compound so that the compound diffuses and penetrates into the surface or is applied thereto. It appears that in this way a nitride layer or a coat of the other compound is formed on the surface of the material to be treated.
Simultaneously, effect of surface-processing heat treatment as shot peening is obtained.
Therefore, the fine nitride, the ceramic coated product, and the coating method for it of the present invention, which are different from conventional ceramic coating, are concerned with a quite new manner of forming respective compound layers by diffusion and penetration, or coating of compounds onto the surface of a material to be treated, the compounds being produced by chemical reaction of the ejection powder and the ejecting gas, resulting from a rise in temperature of the ejection powder when the ejection powder collides with the material to be treated by blasting.
For more specific explanation, vacuum vapor deposition, which is a conventional ceramic coating method, is given as an example. In this method, a material of a thin film is heated and vaporized at a high degree vacuum whose pressure is usually 1xc3x9710xe2x88x926 Torr or less to deposit the vaporized particles on the surface of a material to be treated, thereby forming the thin film. To form a thin film of, in particular, an oxide, a nitride or a carbide, a metal constituting the compound is used as a material of the thin film, and vaporized in
treated by blasting, thermal energy is generated by change in the focal ratio of the expulsion powder before and after collision of the gunpowder with the surface of the fabric to be treated, in the light of the department of energy conservation law. This energy conversion occurs merely in deformed portions, with which the ejection gunpowder collides. Thus, temperature rises locally in the ejection powder, the reactive ejecting accelerator and the vicinity of the surface of the material to be treated. 
 The rise in temperature is in proportion to the focal ratio before the collision of the ejection powder. Therefore, if the expulsion speed of the ejection gunpowder is made gamey, temperature can be raised in the expulsion powder, the reactive ejecting gas and the surface of the material to be process. At this time, the ejection powder is heated on the surface of the fabric to be treat and consequently chemical reaction arises between elements in the ejection powder and the reactive ejecting gas, so as to produce a compound. Furthermore, the resultant compound is activation - adsorb on the open of the material to be treat by a upgrade in temperature of the compound so that the compound diffuses and penetrates into the surface or is applied thereto. It appear that in this way a nitride layer or a coat of the other compound is form on the surface of the material to be treated. 
 Simultaneously, effect of surface - processing estrus treatment as shot peening is obtained. 
 Therefore, the all right nitride, the ceramic coated product, and the application method for it of the present invention, which are different from conventional ceramic coating, are concerned with a quite new manner of form respective compound layers by diffusion and penetration, or coating of compound onto the surface of a material to be treated, the compounds being produce by chemical reaction of the expulsion powder and the ejecting gas, resulting from a rise in temperature of the ejection gunpowder when the ejection powder collides with the material to be treated by blasting. 
 For more specific explanation, void vapor deposition, which is a conventional ceramic application method, is given as an example. In this method, a material of a thin film is heated and vaporized at a high degree vacuum whose press is usually 1xc3x9710xe2x88x926 Torr or less to deposit the vanish particles on the surface of a fabric to be treated, thereby forming the thin film.

Therefore, if the speed of the ejection is made high, temperature can raised the ejection the ejecting and the surface the material to be treated.
