摘要： PROBLEM TO BE SOLVED: To provide a cold spray coating film formation method which can produce a coating film having a high hardness, a high density, and uniform properties throughout the entire coating film. SOLUTION: This cold spray coating film formation method comprises generating a supersonic stream of a gas having a temperature lower than the melting or softening temperature of a spray material, throwing the spray material into the supersonic stream, and colliding the spray material in a solid phase against a substrate at a high speed to form the coating film, wherein a raw material powder for forming the coating film is prepared by mixing a coating film forming powder having a particle diameter of 5 to 50 μm with a peening powder having a particle diameter of 100 to 1,000 μm.

摘要： PROBLEM TO BE SOLVED: To stably use a cooling roll for a log time by providing a soft layer which is high in heat conductivity and whose apparent Young's modulus is specified on an outer circumferential surface of the cooling roll to ensure the uniform cooling in the width direction of a metal strip. SOLUTION: A cooling roll 1 to be used to cool a metal strip is provided with a soft layer 3 on a circumferential surface of a roll body 2 comprising an iron core, and a cooling pipe 4 to distribute a cooling medium inside the soft layer 3. The metal strip is cooled with the cooling medium through the soft layer 3. The soft layer is preferably >=10 W/mK in heat conductivity, 0.01-10 kg/mm in apparent Young's modulus, and 10-1000 times the apparent Young's modulus in thickness. The soft layer 3 is formed by containing high heat conductive fibers in a soft rubber. In the soft layer 3, when the high heat conductive fibers are arranged in a brush shape, preferably the fiber material formed of the high heat conductive fibers is arranged in an inclined manner in the circumferential direction of the cooling roll 1.

摘要： PROBLEM TO BE SOLVED: To obtain a wire rolling guide roller excellent in abrasion resistance, defect resistance, etc., by constructing the guide with a particle-dispersed silicon nitride-based baked body in which Cr2 N particles having a high relative density and a specific average particle size are dispersed in a predetermined volume fraction. SOLUTION: This wire rolling guide roller consisting of a particle-dispersed silicon nitride-based baked body having >=99%, relative density and containing chromium nitride particles having 0.5-10μm average particle size and dispersed in 1-8% volume fraction is obtained by adding a baking assistant (e.g. powdery magnesium oxide) and a predetermined amount of powdery chromium nitride having 0.5-10μm average particle size to powdery silicon nitride, mixing and molding the mixture, then baking the molded body. The dispersed chromium-nitride particles remain in a silicon nitride baked body as hard dispersed particles after baking and have an effect to enhance abrasion resistance by enhancing hardness of the total baked body. Further, the chromium nitride particles have an effect to enhance destruction energy in destruction and have an action to enhance defect resistance by enhancing stiffness, heat and impact resistances.
