The thermalization treatment process of piston component and piston component
Technical field
The present invention relates to Piston Machining technical field, particularly relate to a kind of thermalization treatment process and piston component of piston component.
Background technology
Piston ring is the metal ring of the trench interiors for embedding piston, piston ring for realizing the sealing between piston and cylinder sleeve, with the combustible mixture of sealing combustion indoor.
Due to piston ring in prior art and piston, can not form the condition of self-lubricating between the two and the friction pair of cylinder sleeve, the inwall of cylinder sleeve needs deliberately to process very dark platform reticulate pattern, for storing machine oil, to reach the object of lubrication.But the machine oil that platform reticulate pattern stores can participate in burning, form the problem of carbon distribution.
And because the piston ring coefficient of expansion of the prior art is comparatively large, the opened gap of piston ring is correspondingly also larger.If reduced by the opened gap of piston ring of the prior art, when piston ring expanded by heating in pistons work process, the opening of piston ring closes, and causes piston ring radial swelling, and the gap between piston ring and cylinder sleeve reduces, and then causes the problem of scuffing of cylinder bore.Equally, because the rate of expansion of piston is comparatively large, the gap between piston of the prior art and cylinder sleeve is also larger.Because in prior art, the opened gap of piston ring is larger, and the gap in prior art between piston with cylinder sleeve is also larger, alter under there will be combustion gas or and machine oil on the phenomenon of altering, cause the problem that efficiency of combustion is lower, carbon distribution, consumption of lubricating oil are more, engine power is poor and exhaust emissions is not up to standard.
Therefore, how to solve internal piston in prior art and easily occur carbon distribution, and the problem that the opened gap of piston ring, gap between piston and cylinder sleeve are larger, become those skilled in the art's important technological problems to be solved.
Summary of the invention
The invention provides a kind of thermalization treatment process of piston component, can form the solid-state oil film of one deck on the surface of piston component by the method, this solid-state oil film has good lubricant effect, avoids the problem of machine oil burn soot.And by this thermalization treatment process, effectively can reduce the rate of expansion of piston ring and piston, the opened gap of piston ring and the gap between piston and cylinder sleeve less, effectively can reduce oil consumption and the exhaust emissions amount of fuel oil and machine oil.Present invention also offers a kind of piston component.
The thermalization treatment process of a kind of piston component provided by the invention, comprises step:
By piston ring and | or piston puts into fluid, and is heated by fluid;
In fluid, add powdered alloy, described powdered alloy comprises copper, lanthanum, chromium
,magnesium and element sulphur;
Insulation, soaking time is 7 or 8 hours;
Cooling.
Preferably, fluid is heated to 220 DEG C-300 DEG C.
Preferably, described powdered alloy comprises following element, by percentage to the quality:
Copper 35 ~ 45%, lanthanum 5 ~ 15%, chromium 15 ~ 25%, magnesium 15 ~ 25% and sulphur 5 ~ 15%.
