According to the surface abrasion-resistant treatment method for the speed change gear box gear and the speed changer synchronous gear ring, the surface non-abrasion-resistant problem of the speed change gear box gear and the speed changer synchronous gear ring of an aluminum alloy automobile is solved by generating aluminum oxide ceramic layers of which the hardness is 100 HRB or above on the surface of the speed change gear box gear and the surface of the speed changer synchronous gear ring; the safety and the reliability are achieved, and the abrasion resistance is very high; the production cost of the speed change gear box gear and the speed changer synchronous gear ring of the automobile can be reduced through the method, the service life of the speed change gear box gear and the service life of the speed changer synchronous gear ring are prolonged, and economic benefits and social benefits are very good.
Description
Technical field
The present invention relates to the wear resistant processing method for surface of a kind of aluminium alloy automobile change gear box gear and variator synchronizing tooth ring product。
Background technology
Current automobile speed change gearbox gear and the variator synchronizing tooth ring overwhelming majority are all adopt copper material to produce, and cost is high, wearability neither be very good。Also having a little part is adopt steel material to produce, but because has and easily produce glue make and non-spread with axle。And aluminium alloy automobile change gear box gear and variator synchronizing tooth ring also do not come into operation, main cause is exactly that its surface abrasion resistance does not reach requirement。And the present invention just can solve aluminium alloy automobile change gear box gear and the problem of variator synchronizing tooth ring surface abrasion resistance。
Summary of the invention
A kind of change gear box gear and variator synchronizing tooth ring wear resistant processing method for surface are it is an object of the invention to provide。The present invention adopts electrochemical method to reach the alumina ceramic layer of more than HRB100 in aluminium alloy automobile change gear box gear and a kind of hardness of variator synchronizing tooth ring Surface Creation, and method safety is reliable。
In order to solve above-mentioned technical problem, inventor is screened by test of many times repetition test, finally chooses the alumina ceramic layer adopting electrochemical method to reach more than HRB100 in aluminium alloy automobile change gear box gear and a kind of hardness of variator synchronizing tooth ring Surface Creation。Because ceramic layer hardness significantly high (more than more than HRB100) just can reach wear-resisting purpose。Thus the problem solving its surface abrasion resistance。
The technical scheme is that a kind of change gear box gear and variator synchronizing tooth ring wear resistant processing method for surface, it is characterized in that comprising the steps of
(1) by after good for strong for the tensile strength superelevation more than 680MPa aluminum alloy forged and heat treatment, then aluminium alloy automobile change gear box gear and variator synchronizing tooth ring are placed on Special hanger；
(2) aluminium alloy automobile change gear box gear and variator synchronizing tooth ring are put in clear water and soak 1～5 minute；
(3) ungrease treatment 1～10 minute in alkaline solution；
(4) clear water cleans 1～3 minute；
(5) 1～8 minute is soaked in an acidic solution；
(6) put in an energising tank liquor and process 40～100 minutes；
(7) put in clear water and soak 1～5 minute；
(8) natural air drying or drying can form the alumina ceramic layer of 60～200um at aluminium alloy automobile change gear box gear and variator synchronizing tooth ring surface, and case hardness reaches more than HRB100。
Beneficial effects of the present invention:
Because aluminium-fre e alloy automobile speed change gearbox gear and variator synchronizing tooth ring product on market, therefore can only compare with copper ring gear, the invention solves aluminium alloy automobile change gear box gear and variator synchronizing tooth ring surface abrasion resistance sex chromosome mosaicism, it is possible to replace copper ring gear with aluminium alloy automobile change gear box gear and variator synchronizing tooth ring。Save cost, life-saving。There is very good economic benefit and social benefit。
Detailed description of the invention
Below in conjunction with detailed description of the invention, the present invention is described in further detail:
Process route:
1. by after good for strong for the tensile strength superelevation more than 680MPa aluminum alloy forged and heat treatment, then aluminium alloy automobile change gear box gear and variator synchronizing tooth ring are placed on Special hanger。
2. aluminium alloy automobile change gear box gear and variator synchronizing tooth ring are put in clear water and soak 1～5 minute。
3. ungrease treatment 1～10 minute in alkaline solution (formula: containing NaOH:50～300 gram in every liter of solution)。
4. clear water cleans 1～3 minute。
5. soak 1～8 minute in acid solution (formula: containing HNO3:100～400 gram in every liter of solution)。
6. put in an energising tank liquor, formula by weight percentage: the H of 6～18%2SO4The Na of+1～6%2HC6H5O7The H of+1～17%3BO3；Voltage is 15～120V；Electric current is 0.3A～3A/dm2。Process 40～100 minutes。
7. put in clear water and soak 1～5 minute。
8. natural air drying or drying。
Just can be formed the alumina ceramic layer of 60～200um at aluminium alloy automobile change gear box gear and variator synchronizing tooth ring surface by above-mentioned technique。Case hardness reaches more than HRB100。Owing to the hardness of oxide layer is very high, the anti-wear performance of part therefore just can be improved。
Therefore the embodiment that the above-mentioned only present invention is preferably feasible, non-limit to scope, is done various deformation according to above-described embodiment or applies mechanically all within this technical scheme protection domain。
