Abstract:
PROBLEM TO BE SOLVED: To provide a coating other than chrome coating giving the same performance as that of the chrome coating while the utilization of the coating other than the chrome coating is possible. SOLUTION: The substrate 12, and the article 10 composed of the cobalt-phosphorus coating 14 applied on the substrate are heat-treated. The at least one physical property of the cobalt-phosphorus coating 14 is changed, and eventually the performance characteristics of the cobalt-phosphorus coating 14 are changed by the heat treatment. The article can be a component of an actuator having, for example, a bore, and a shaft at least partially and movably disposed in the bore. COPYRIGHT: (C)2009,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To provide a wear-resistant device for coping with various forms of wear mechanism. SOLUTION: A wear-resistant device 120 includes a substrate 50 and a wear-resistant layer 22 arranged on the substrate 50. The wear-resistant layer 22 includes a matrix 24, particulates 26 diffused in the whole matrix 24, and a boron material. The wear-resistant layer 22 is subjected to boronizing to diffuse boron in the matrix 24. The temperature of the boronizing can be selected so as to add the advantage of mutually diffusing the particulates 26 and the matrix 24 to strengthen the bond. The temperature of boronizing selected depends on the type of material selected as the substrate 50. COPYRIGHT: (C)2011,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To provide a titanium component having high resistance to both fatigue stress and wear. SOLUTION: A metallic layer 16 is formed on a titanium substrate 14. Next, the metallic layer 16 and the titanium substrate 14 are diffused together to form a diffusion region. The diffusion consolidates the metallic layer 16 through atomic transport to fill microvoids in the metallic layer 16. Thereafter, mechanical working such as peening and rolling is performed to establish a residual stress region 24 that extends through the metallic layer 16, the diffusion region, and at least partially into the titanium substrate 14.

Abstract:
PROBLEM TO BE SOLVED: To provide a tribological coating to be used on a bearing surface. SOLUTION: A method of forming a bearing coating includes a step of depositing a porous layer 26 on a substrate and a step of depositing a lubricating material within pores of the porous layer. The porous layer 26 and the lubricating material 28 form a bearing coating 24 on the substrate. The bearing coating 24 includes between about 1 vol% and about 20 vol% of the lubricating material with the balance being the porous layer. COPYRIGHT: (C)2008,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To provide a coating method which is substituted for the conventional chromium plating. SOLUTION: The coating method comprises: a step of providing an article to be coated; a step of providing an electroplating bath solution having a chemical composition composed of about 180 to 210 g/l of cobalt chloride, about 0.05 to 2.0 g/l of cobalt carbonate, about 45 to 55 g/l of ortho-phosphoric acid and about 5.0 to 15.0 g/l of phosphorus acid; and a step of placing the article in contact with the plating bath solution and applying a current to laminate a coating onto the article.

Abstract:
A butterfly valve (10) comprises a housing including a bore (12), a rotatable shaft (16) passing through the bore (12), a disc (14) mounted to the shaft (16) for controlling the flow of a fluid through the bore (12), a thrust load reacting section (26) and a wear interface (30). The thrust load reacting section (26) includes a thrust plug (32) assembled in a thrust reacting end of the shaft (16) and a thrust plate (28) secured to the housing. The thrust plate (28) has a well (40) for axially retaining the thrust plug (32) and the thrust reacting end of the shaft (16). The wear interface (30) includes a first contact region on the thrust plug with a first contact surface (38B) and a second contact region at the base of the well (40) with a second contact surface (38A). A portion of the first contact surface (38B) is spherical and in contact with a portion of the second contact surface (38A).
