| titleOfInvention | High hardness surface coating method of metal article |
| abstract | The present invention relates to a high hardness surface coating method for metal parts, More particularly, the present invention relates to a method for nitriding a surface of a base material by heat-treating a base metal material of a metal part at a temperature of 500 to 650 占 폚 with a nitriding gas composed of nitrogen gas, ammonia gas or a mixed gas thereof; And The nitrided metal part base material is charged into the rotatable chamber, a mixture of the metal halide catalyst and the metal powder is charged into the chamber, the temperature inside the chamber is raised to 800 to 1100 ° C, And a step of depositing a metal nitride on the surface of the base material to form a high-hardness nitrided coating layer on the metal part. According to the coating method of the present invention, a nitrided layer is formed on the surface of the metal part base material by nitriding treatment, and a metal nitride is deposited on the surface of the metal part base material by surface coating again to form a nitrided coating layer, The bonding strength can be improved and the hardness of the surface can be remarkably improved. |
