Abstract
A martensitic stainless steel holder electropolishing technic comprises the steps of firstly pre-processing with prescription; 20% to 25% H2SO4, 5% to 8% HCl, 3% to 7% HNO3, 1% to 2# glycerin, residual distilled water; dipping the holder 3 to 8 minutes, peeling off, removing water after washed by flowing water; polishing electrochemically with prescription; 50% to 60% H3PO4, 10% to 18% H2SO4, 4% to 8% CrO3, 14% to 18% glycerin, residual distilled water; adding H3PO4 proportionally after dissolving CrO3 in the distilled water, then adding H2SO3 slowly, agitating evenly; stabilizing 10 minutes, adding slight glycerin gradually by several times, putting the holder in to polishing groove; temperature is 85 deg C to 95 deg C, current intensity 8 A/dm2 to 15A/dm2, time 5minutes to 10minutes; washing with flowing water after polishing, then neutralizing with 5% Na2CO3 solution, drying after dewatering by ethanol solution.
Description
Technical field
The invention belongs to technical field of surface, specially refer to a kind of Martensite Stainless Steel retainer electrolytic brightening process.
Background technology
Domestic existing technology is many, but in the practical application, its polishing effect is unsatisfactory, promptly adopts existing technology that the Martensite Stainless Steel retainer is carried out polished finish, can not obtain the outward appearance of ideal uniform light.
Summary of the invention
For addressing the above problem, the present invention proposes a kind of Martensite Stainless Steel retainer electrolytic brightening process, this technology is improved glossing and is obtained comparatively ideal polishing effect by improving the prescription of polishing fluid.
For achieving the above object, the present invention has adopted following technical scheme:
Described Martensite Stainless Steel retainer electrolytic brightening process adopts the mode of twice processing, at first by pre-treatment, realizes by electrochemical etching, wherein again
I, pre-treatment
I, pretreatment fluid are filled a prescription by volume, and per-cent consists of: 20～25%H
2SO
4, 5～8%HCL, 3～7%HNO
3, 1～2% glycerine, distilled water surplus;
H in ii, the above-mentioned pretreatment fluid prescription
2SO
4, HCL, HNO
3Can remove retainer surface scale and greasy dirt, glycerine prevents excessive erosion, and the Martensite Stainless Steel retainer is immersed in this pretreatment fluid 3～8 minutes till oxide skin is removed, and after flowing water cleans, removes moisture;
II, electrochemical etching
I, electrochemical etching liquid formula consist of by mass percentage: 50～60%H
3PO
4, 10～18%H
2SO
4, 4～8%CrO
3, 14～18% glycerine, distilled water surplus;
Ii, electrochemical polish liquid process for preparation: use earlier dissolved in distilled water CrO
3, add H then in proportion
3PO
4, and stir, slowly add H again
2SO
3, and stir; Stablized ten minutes, and added slightly that glycerine reacted again, glycerine must progressively add in the solution several times on a small quantity;
Iii, polishing: the Martensite Stainless Steel retainer is put into polishing trough polish; Temperature is 85 ℃～95 ℃, and strength of current is 8～15A/dm
2, the time is 5～10 minutes, negative electrode is a stereotype; The polishing back is cleaned with flowing water, uses 5%Na then
2CO
3The solution neutralization cleans up with flowing water, dries after anhydrating with ethanolic soln to get final product on dryer again.
Because adopt aforesaid technical scheme, the present invention has following superiority:
Above technology is practical through actual Martensite Stainless Steel retainer polishing check, workpiece homogeneous light.
