Abstract
The invention relates to a martensitic stainless steel piston ring coloring method. It includes the following steps: hanging; cleaning; processing liquid blasting; fresh water rinsing; hot water rinsing; blowing; heating in heating furnace; dropping into distilled water; heating at different temperature to gain different colors compact oxide film; and taking out. The invention adopts direct oxidation process, and has no pollution. The color is easy to control. And the operation is simple. The invention is the convenient and practical martensitic stainless steel piston ring coloring method.
Description
1, technical field:
The present invention is a kind of colorize method of Martensite Stainless Steel piston ring, particularly a kind of colorize method of Martensite Stainless Steel piston ring.
2, background technology:
Along with the raising of people's living standard, motorcycle at home sale and just use speed increment with at double.And piston ring is the major part and the consumable accessory of motorcycle IC engine, in use, piston ring is very easy to wear, cause motor performance to descend greatly after the wearing and tearing, phenomenons such as poor air-tightness, scuffing of cylinder bore, engine be unable appear, thereby oil consumption is increased, and power reduces, and has a strong impact on the normal operation of engine.Therefore, all take much count of improving the research in piston ring life-span both at home and abroad, and doing a lot of work aspect piston ring material and surface working and the surface Hardening Treatment.Many on the market at present piston ring adopt Martensite Stainless Steel to make, mainly be the characteristics of utilizing its vibration damping good, add different painted treatment process after the stainless steel piston ring thermal treatment again, can obtain gorgeous colour film, these colour films are made up of metal oxide, they promptly play beauty function, play antirust again and antifriction function.
Stainless painted research originates in nineteen twenty-seven, from that time, people are carrying out unremitting research to Color Stainless Steel always, stainless colorize method is a lot, but main approaches can be divided into two big classes: chemical coloring process and electrochemical coloring method, wherein studying maximum is chemical method, INCO method just, it is that stainless steel is immersed in the chemical pigmenting liquid, form a kind of colour film by chemical spontaneous reaction at stainless steel surface, this method has obtained application in actual production, but because this method is polluted comparatively serious, and color control device complexity, not easy to operate, especially for Martensite Stainless Steel, painted difficulty is bigger, so the insider has begun the exploration of some other novel methods now, try hard to change above these deficiencies both at home and abroad.
3, summary of the invention:
The objective of the invention is to overcome above-mentioned shortcoming and a kind of colorize method that adopts direct oxidation method to form colour film on Martensite Stainless Steel piston ring surface is provided.The present invention does not pollute, and color control is simple, easy to operate.
The colorize method of Martensite Stainless Steel piston ring of the present invention comprises the steps:
1) hangs piston ring;
2) cleaning piston ring;
3) piston ring being carried out liquid blasting handles;
4) clear water rinsing piston ring;
5) with hot water cleaning piston ring;
6) dry up piston ring;
7) piston ring after the cleaning places process furnace to heat with hang, splashes into distilled water simultaneously, through the differing temps heat tracing, can obtain the dense oxidation film of different colours;
8) piston ring is taken out from process furnace.
The Heating temperature of above-mentioned piston ring in process furnace is 300 ℃～430 ℃.
The above-mentioned distilled water speed that splashes into is 8～12 droplets/minute.
The heat-up time of above-mentioned piston ring in process furnace is 50～60 minutes.
Aforesaid liquid sandblasting material therefor is a quartz sand, and quartz sand size is 350 orders～450 orders.
The present invention is owing to adopt direct oxidation method to form the colorize method of colour film on Martensite Stainless Steel piston ring surface, and the present invention does not pollute, and color control is simple, easy to operate.The present invention is a kind of colorize method of convenient and practical Martensite Stainless Steel piston ring.
4, embodiment:
Embodiment 1:
The colorize method of Martensite Stainless Steel piston ring of the present invention comprises the steps:
1) hang piston ring, in the present embodiment, the piston ring material therefor is the 6Cr13Mo Martensite Stainless Steel;
2) cleaning piston ring;
3) piston ring is carried out liquid blasting and handle, its objective is cleaning piston ring surface, and the favorable mechanical activation is arranged; It is quartz sand that material therefor is handled in liquid blasting, and quartz sand size is 350 orders～450 orders, and in the present embodiment, the granularity of quartz sand is 400 orders.
4) clear water rinsing piston ring;
5) with hot water cleaning piston ring;
6) dry up piston ring;
7) piston ring after the cleaning places process furnace to heat with hang, and the Heating temperature of piston ring in process furnace is 300 ℃～430 ℃, and be 50～60 minutes heat-up time.In addition, in heat-processed, splash into distilled water simultaneously,, can obtain the dense oxidation film of different colours through the differing temps heat tracing; The effect that oxidising process splashes into distilled water is the oxidation catalyst that changes piston ring, makes the oxide film even compact.The above-mentioned distilled water speed that splashes into is 8～12 droplets/minute.In the present embodiment, the Heating temperature of piston ring in process furnace is 380 ℃, and be 55 minutes heat-up time.Splashing into distilled water speed is 10 droplets/minute.
8) piston ring is taken out from process furnace, piston ring can obtain golden yellow oxide film.
Embodiment 2:
The colorize method of Martensite Stainless Steel piston ring of the present invention is identical with embodiment 1, and difference is that the Heating temperature of piston ring in process furnace is 400 ℃, and piston ring can obtain sky blue oxide film.
