Abstract
The utility model discloses a self-lubricating ball with a lubricating composite layer, consisting of a ball body, a substrate layer 1 and a cladding layer WS2-layer-2. The self-lubricating ball solves the problem that when the existing ball is used, the applied common lubricating agent is easily deteriorated due to the influence of the environment, thus influencing the lubricating effect. The obtained ball has self-lubricating effect and low friction coefficient, does not need to match and use other lubricating agents, has corrosion resistance, can bear the adverse influence in the application environment, also can operate normally at high temperature and overcome the influence of high temperature generated by high-speed movement on the general lubricating material.
Description
Technical field
The utility model relates to a kind of ball, especially a kind of ball that has lubricated composite bed.
Background technique
Ball is a moving element commonly used in the bearing, such as the steel ball in bicycle or the Motor Vehicle bearing, adds usually when liquid lubrication is used for the ball motion, reduces friction.But in infiltration, be stained with ash, and because high-speed motion produces under the situation of high temperature, lubricant oil is perishable, causes the lubrication effect between the ball to descend, frictional force increases, and causes whole parts to use when serious.
Summary of the invention
The utility model provides a kind of selflubricating ball, can overcome because the defective of using liquid oils to bring is achieved through the following technical solutions:
A kind of selflubricating ball is that base material is made by the treated steel ball in surface, and this steel ball surface is coated with the wearing layer of base layer (1) and coating layer (2) composition.
Described base layer (1) is TiN (titanium nitride) layer, and thickness is 0.01 μ m-10 μ m; Preferred thickness is 0.1 μ m.
Described coating layer (2) is WS
2(tungsten disulfide) layer, thickness is 0.01 μ m-10 μ m; Preferred thickness is 0.3 μ m.
Described base layer (1) with the combination of ball is: with the metal vapor vacuum arc source technology, the TiN coating to the ball surface, is formed wear-resisting base layer (1).
Described coating layer (2) with the combination of the ball that is coated with base layer (1) is: in the radio-frequency sputtering mode in the physical gas phase deposition technology, with WS
2Coating forms wear-resisting coating layer (2) to described base layer (1) surface.
Described ball diameter is 5mm-12mm, is preferably 8mm.
The utility model adopts the base layer of TiN as the ball surface, because TiN coating hardness height, wear resistance is good, has good corrosion prevention performance.In addition, general surperficial enhancement technique is that this strengthened layer and matrix have tangible interface, often occur the coating shedding phenomenon in application at material surface coating one deck strengthened layer.And in the utility model, the ion implantation technique of employing is that selected intensified element ionization is processed into ion, quickens by high voltage again, injects matrix surface, forms the modified layer of strengthening, and does not have separating surface with matrix, does not have the sorrow that comes off.Combination force is good between modified layer and matrix, obtains good modified effect thus.TiN is coated in steel ball body 3 with ion implantation technique, forms base layer 1, combine with body 3 effective, difficult drop-off, and make the steel ball surface have hard and the corrosion-resistant effect.
WS
2Have lubricity and resistance to high temperature.Adopt micron order, highly purified WS
2As raw material, in the radio-frequency sputtering mode in the physical gas phase deposition technology, with WS
2Coating forms the coating layer 2 of lubricating and wear-resisting to base layer 1 surface of steel ball.With base layer affinity height, can reduce friction factor, strengthen wear-resisting property, and can anti-650 ℃ of high temperature.
The ball that obtains with the utility model has self-lubricating effect, and friction factor is low, does not need being used of other lubricant oil, and corrosion-resistant, the harmful effect in the tolerance applied environment.Solved existing problem in the prior art.And the operation that can at high temperature do as usual overcomes the influence of the high temperature of high-speed motion generation to general lubriation material.
