Abstract:
A TiAlN / BN multilayer hard thin film is provided to improve the hardness and thermal stability at the same time. A hard multi-layered thin film with a superior thermal stability by using the unbalanced magnetron sputtering apparatus in which two targets are faced. One target of the apparatus is made of the TiAl alloy controlling the aluminum content, the other one is BN. The content of the aluminum within the TiAl target characterizes to do to 50 atomic percentage.
Abstract:
A method for depositing for coating on the surface and the apparatus is provided to deposit on the surface of the substrate introducing the reaction gas and is mounted on anode and serves both the bipolar role for being thus used are provided. A discharge in the space supplying the direct current voltage between the cathode(1) and the anode(2) which is installed in order to be faced with each other within the reaction chamber(5) and goes with electrode are disclosed, material is deposited on the surface of the substrate introducing the reaction gas and is mounted on anode and serves both the bipolar role. A method for depositing material at the state excluding a positive column(4) conducted as follows: a cathode glow(8) and anode glow(9) exist as the coating layer form coating the respective cathode and substrate surface; and the material is deposited in the small state as much as the positive column does not exist or it can ignore.

Abstract:
PURPOSE: A bent hard surface smoothing method using a laser with a focus is provided to remove an irregular portion selectively and promptly. CONSTITUTION: A laser(12) with a focus formed by a lens(13) is scanned on the rough surface. Herein, the degree of focus and the laser influence of the scanned laser beam are varied corresponding to positions and so is the removal speed of the substances on the surface. The position becomes higher, and then the removal of the substances grows faster. After the removal of the high position, the focus of the laser is lowered gradually to scan the entire of the surface. According to the processing with the laser, the degree of smoothness is enhanced.

PURPOSE: A cutting tool coated with diamond film and a producing method thereof are provided to obtain sufficient adhesive force without limitation of the content of decarbonate and carbon monoxide of base material. CONSTITUTION: Decarbonating thermal treatment and carbonate thermal treatment are applied on a carbide base material to increase the roughness of surface of the carbide base material with abnormal particle growth. A diamond film is layered on the surface of the base material to improve the adhesive force of the diamond film. Thereby, a cutting tool coated with diamond film of sufficient adhesive force is produced without limitation of the content of decarbonate and cobalt of base material and without limitation of the size of carbide particle.
