Description
Technical field:
The invention belongs to one important spare part piston ring of automobile engine, its be specifically related to one " nitrogenize "+" PVD " multiple
Close coating concave-concave tang piston ring.
Background technology:
It is known that along with automobile volume of production and marketing constantly rises, auto Parts Industry is risen the most therewith, day must be met increasingly
Acute automobile production industry, is exactly after market subsequently.Manufacture automobile engine all kinds of resource transition consumption useless, environment for human survival day
Benefit is contaminated, and the most day by day becomes the obstacle of modernization, also result in countries in the world and the great attention of expert at different levels.Respectively
Resource reasonable development is effectively utilized and refer to important process schedule and human setting house development meter with the depollution of environment by state government equally
Most important position in Huaing.Electromotor, as the core component of the vehicles, is that power consumption total amount is most at present, and discharge amount of exhaust gas is maximum
Power product.And the utilization of the how many pairs of social energy of the harmful gas of effective work efficiency size of electromotor and discharge and
Environmental Kuznets Curves serves vital effect.To this end, countries in the world have put into effect engine emission standard, Environmental Protection in China the most in succession
General bureau has also promulgated mandatory discharge standard.Therefore traditional gap-clearance of piston rings shape and sealing far from adapting at present is pass by
This high leakproofness of electromotor, the requirement of low emission.Want to meet above-mentioned performance and requirement is necessary for using opening to have close
The good technology requirement of envelope property, can meet piston ring wearability, close by nitridation+PVD composite coating concave-concave tang structure treatment
Envelope property and discharge performance thereof.
Summary of the invention:
Technical solution of the present invention, can improve the wearability of piston ring, sealing, effectively reduces the noxious emission of automobile；
A kind of " nitridation "+" PVD " composite coating concave-concave its structure of tang piston ring is mainly by basic ring (1), nitration case first
Individual hardened layer (2) and second hardened layer (3) of nitration case, PVD coating (4), spill (5,7,8), convex (6,9,10) is constituted, institute
This composite coating concave-concave tang piston ring stated is characterized in that: basic ring (1) exosmosis two-layer nitration case, i.e. nitration case first
Hardened layer (2) and second hardened layer (3) of nitration case, spray one layer of PVD coating the most again second hardened layer (3) of nitration case
(4), this gap-clearance of piston rings uses spill (5,7,8) and convex (6,9,10) structure.
For reaching above-mentioned purpose, by carrying out pre-treatment around the piston ring basic circle made by nitridation requirement, then nitrogenize,
Carry out repairing mouth, cross grinding, cylindrical lapping after nitridation, when removing piston ring nitridation outside produced oxide-film, and requirement
Circle roughness reaches PVD technique and processes requirement；
In such scheme, this nitridation+PVD composite coating concave-concave tang piston ring surface carries out concave-concave after being disposed
Tang is processed, and the piston ring being fabricated to this concave-concave tang structure not only increases piston ring wearability, sealing, the most also drops
The low harmful gas of engine emission, thus reach the purpose of increasing service life of engine, and then also reach economic benefit
And the situation of social benefit multi-win.
Accompanying drawing illustrates:
Fig. 1 is that one of the present invention nitrogenizes+PVD composite coating concave-concave tang piston ring structure schematic diagram
Detailed description of the invention:
Below in conjunction with the accompanying drawings one of the present invention nitridation+PVD composite coating concave-concave tang piston ring is made the most specifically
Bright, this composite coating concave-concave tang piston ring is mainly by basic ring (1), first hardened layer (2) of nitration case and nitration case second
Hardened layer (3), PVD coating (4), spill (5,7,8), convex (6,9,10) is constituted；
Described this composite coating concave-concave tang piston ring is characterized in that: basic ring (1) exosmosis two-layer nitration case, i.e. nitrogen
Change first hardened layer (2) of layer and second hardened layer (3) of nitration case, spray one the most again second hardened layer (3) of nitration case
Layer PVD coating (4), this gap-clearance of piston rings uses spill (5,7,8) and convex (6,9,10) structure.
The technical program one nitridation+PVD composite coating concave-concave tang piston ring machining path is: shape steel line
---around basic ring,---------------deoil face grinding otch material---pickling---drying---the GN 2 in setting in destressing
------cylindrical lapping---deoils and---dries---PVD process---and be finally processed into concave-concave tang shape structure to repair mouth in change.This
Nitridation+PVD composite coating concave-concave tang piston ring surface carries out concave-concave tang processing after being disposed, and is fabricated to this concave-concave convex
The piston ring of mouth structure not only increases piston ring wearability, sealing, also reduces the harmful gas of engine emission simultaneously,
Thus reach the purpose of increasing service life of engine, and then also reach economic benefit and the situation of social benefit multi-win.
