摘要:
A technique for using an iron plating for coating an aluminum product that results in adequate durability. An aluminum piston (10) used as a plated aluminum product is covered by an iron-based composite plating layer (11). The iron-based composite plating layer (11) contains a carbon nanomaterial, which is applied to the aluminum-based base material using a iron-based composite plating bath formed by mixing a carbon nanomaterial into an iron plating bath.

PROBLEM TO BE SOLVED: To provide a sliding bearing having performance equal to or more than that of a rolling bearing, the rolling bearing used for a scroll compressor loaded on an automobile being replaced by the sliding bearing.SOLUTION: In this sliding bearing, a sliding layer is formed by burning on a back metal thereof. The sliding layer is made of 5-60 wt.% graphite, average radius of which is 5-50 μm, degree of graphitization of which is 0.6 or more, in which an average shape coefficient (Y) defined as in the following of particles except fine particles each having a radius of 0.5 times or less of the average radius is 1-4, and which includes particles having a shape coefficient (Y) within a range (Y)=1-1.5 at 70% or more in the ratio of the number, and polyimide resin and/or polyamideimide resin as residues.

PROBLEM TO BE SOLVED: To provide a piston for an in-cylinder fuel-injection type internal combustion engine having a low thermal conductive material capable of further improving heat insulating property. SOLUTION: This piston for in-cylinder fuel-injection type internal combustion engine has a low thermal conductive member comprising low thermal conductive base material, and coating layer including alumina (Al 2 O 3 ) fine particles adhering on at least part of a cast-in surface cast in a piston body part at one surface side of the low thermal conductive base material cast in a piston top part. A heat insulating layer comprising the coating layer and or an air gap layer caused by the same is formed between the low thermal conductive member and the piston body thereby. As a result, low thermal conductivity of a fuel impingement zone can be easily improved as compared to a case that the low thermal conductive member is simply cast in. COPYRIGHT: (C)2010,JPO&INPIT
