Abstract
The invention relates to a processing method of high-wear-resistance laser-reinforced material for piston rings and relates to the technical field of surface treatment of piston rings. An in-situ synthesized particle-reinforced composite coating is arranged on the surface of a circular piston body by means of laser-reinforced material manufacturing. The piston ring produced by new fast three-dimensional solid freeform technology and applying the laser technology to the technique of piston ring surface processing is controllable in shape, texture and performance. In addition, the in-situ synthesized particle-reinforced composite coating is excellent in wear resistance, fine in stability, highly combinable with base material, so that the novel piston ring features high wear resistance greatly prolonged lifetime.
Description
Technical field
The present invention relates to the technical field of surface of piston ring.
Background technology
Frictional contact surface when piston ring uses is its periphery, because piston ring to-and-fro movement continually, so often because friction causes fret wear, is out of shape even tears, influence piston ring packing.Existing wear resistance piston ring utilizes mode such as plating at the periphery wear-resistant coating of pot type piston ring usually, and as hard chrome coating, ceramic membrane, metastable state amorphous carbon coating, but still there is the problem that wears no resistance in the product of this process forming.
Summary of the invention
The object of the invention is exactly to propose a kind of laser that can effectively improve the wear resistance of piston ring excircle face to increase the material manufacture method.
The present invention adopts laser to increase the material manufacture method, original position synthesis particle is set on the surface of annular piston main body strengthens compound coating.
The present invention is applied to laser technology in the piston ring process of surface treatment, adopts quick three-dimensional entity fast free shaping new technology, and the piston ring shape of preparation, tissue, performance are all controlled.In addition, original position synthesis particle strengthens compound coating and has the excellent abrasive energy, good stability, and strong with the bonding force of base material, make novel piston ring have the high abrasion feature, greatly improve work-ing life.
In order further to ensure the wear resistance of product surface, the Vickers' hardness that original position synthesis particle of the present invention strengthens compound coating is HV850～1200.
In like manner, the thickness of original position synthesis particle enhancing compound coating of the present invention is 0.08～0.60mm.
Embodiment
By the research to high-grade piston ring working conditions, determine the performance that it is required, utilize computer to set up three-dimensional model, and implement laser in the piston ring surface of semi-finished and increase the material manufacturing, comprise technique means such as laser alloying and laser melting coating, it is controlled to prepare shape, tissue, performance, has the piston ring that original position synthesis particle strengthens compound coating.
Original position synthesis particle is set on the surface of annular piston main body strengthens compound coating, the Vickers' hardness that this original position synthesis particle strengthens compound coating is that HV850～1200, thickness are 0.08～0.60mm.
And then through thermal treatment, milling mouth, rough bore, slightly repair mouth, cylindrical grinding, right boring hole, refine mouth, phosphatization, oil, form final high abrasion piston ring.
Claims (3)
1. the high abrasion laser of piston ring increases material processing method, it is characterized in that: adopt laser to increase the material manufacture method, original position synthesis particle is set on the surface of annular piston main body strengthens compound coating.
2. the high abrasion laser according to the described piston ring of claim 1 increases material processing method, it is characterized in that the Vickers' hardness of described original position synthesis particle enhancing compound coating is HV850～1200.
3. the high abrasion laser according to claim 1 or 2 described piston ring increases material processing method, it is characterized in that the thickness of described original position synthesis particle enhancing compound coating is 0.08～0.60mm.
