Description
Technical field
The present invention relates to a kind of wear-resisting slide unit, for example be used for the piston ring and the cylinder sleeve of oil engine.
Background technology
Recently, the strong request oil engine has higher power and performance.Slide unit, the working conditions that for example is used for the piston ring of oil engine and cylinder sleeve is abominable day by day, therefore, requires each slide unit to have higher wear resistance and antifraying property.
Traditionally, adopt chromium plating to handle the wear resistance that improves slide unit.But the antifraying property that can not substantially improve slide unit is handled in chromium plating, and therefore, this technology is tending towards being replaced by spray treatment.For example, JP6-221438 has proposed to form on a kind of periphery sliding surface that is coated in piston ring by plasma spray the technology of sprayed coating, and wherein, this sprayed coating comprises molybdenum, nickel-chromium alloy and tiny chromium carbide powder.
Owing to contain described ceramic powder in the sprayed coating, therefore, the slip drag of above-mentioned piston ring increases.And, also exist ceramic powder to attack pair materials, cause the problem of barrel wear.
Summary of the invention
The objective of the invention is to address the above problem and provide to be formed with to prevent that the sliding stop drag increases and attack the wear-resisting slide unit of the thermally sprayed coating of joining duplicate.
Therefore, according to the present invention, a kind of slide unit has matrix metal and is formed on the sprayed coating on the sliding surface outside the matrix metal.Coating is prepared from by spraying a kind of mixture, and this mixture contains, in mass: 30-70% molybdenum powder, 10-40% nickel-chromium alloy powder, 3-40% ceramic powder and 2-15% solid lubricant powder.
The content of molybdenum powder is that the reason of 30-70% (quality) is: when molybdenum powder content was lower than 30%, the antifraying property of coating descended.And when molybdenum powder content surpassed 70%, coating was difficult to obtain enough hardness.
The content of nickel-chromium alloy powder is that the reason of 10-40% (quality) is: when the nickel-chromium alloy content of powder was lower than 10%, coating was difficult to obtain enough tenacityes.And when the nickel-chromium alloy content of powder surpassed 40%, the antifraying property of coating descended.
The content of ceramic powder is that the reason of 3-40% (quality) is: when ceramic powder content was lower than 3%, coating was difficult to obtain enough hardness.And when ceramic powder content surpassed 40%, coating was too hard, attacked easily and joined duplicate.
The content of solid lubricant powder is that the reason of 2-15% (quality) is: when the solid lubricant content of powder was lower than 2%, lubricant effect was too not enough, can not prevent that the increase of slip drag and the attack of coating from joining duplicate.And when the solid lubricant content of powder surpassed 15%, coating became fragile.
Wear-resisting slide unit of the present invention is prepared from by form sprayed coating on the sliding surface of parts, described sprayed coating obtains by spraying a kind of mixture that is made of molybdenum powder, nickel-chromium alloy powder, ceramic powder and solid lubricant powder, cause these parts to have more excellent wear resistance and antifraying property, and, owing to have the solid lubricant powder in the coating, compare with the spraying slide unit in the aforementioned reference, its aggressiveness to pair materials is lower.As a result, described parts are very favourable as the parts such as piston ring in high-performance, the large-sized ocean diesel engine.A special advantage is that this coating can prolong engine life.
