Description
Technical field
The present invention relates to a kind of mechanical zinc-plating steel piece heat to ooze with encapsulant, belong to Surface thermo-chemical treatment and the coating technology field of ferrous materials.
Background technology
Zinc coat, for dip galvanized, has the advantages such as infiltration layer is even, hardness is high, wear resisting property is good, thickness is controlled, dimensional precision is higher, corrosion resistance nature is better.It is suitable for dimensional precision has certain cooperation to require and requires the part of corrosion resistance nature height and certain wear resisting property, is widely used in mechanical component and some middle-size and small-size structural part, the pipe fittings such as fastening piece, spring, valve, axle, pin, chain, gear.
Traditional zincizing technique is common with sherardise, sherardise is in the retort or zincizing case zincizing agent and steel piece being loaded by a certain percentage roll (or rotation), be heated to about 400 DEG C, under the condition of insulation, the part of retort or zincizing case and filler ceaselessly collided and rub, metallic zinc in penetration enhancer produces active zinc atom on steel piece surface, active zinc atomic adsorption is to steel surface, then zinc atom diffuses into steel substrate and forms zinc-iron alloy layer, iron atom also passes zinc-iron alloy layer to external diffusion simultaneously, form the mutual diffusion reaction of zinc-iron, final formation infiltration layer.Sherardise will reach certain alloying layer thickness then needs certain heating or soaking time, even if zincizing under vacuum, still needs insulation 4 ~ 6 hours, even needs insulation 8 ~ 10 hours for complex-shaped workpiece, therefore cause its production efficiency undesirable; In addition, the product scrap rate of sherardise is high; These affect the application and development of this technology always.
In order to improve yield rate and the production efficiency of steel piece zincizing, there has been proposed zincizing technology after plating, namely first zinc-plated in advance on steel piece surface, then carry out thermodiffusion and obtain zinc coat.The thickness of coating of electro-galvanizing is thinner, and the zinc coat formed after diffusion is also thin, and corrosion fatigue life is limited, is not suitable as pre-zinc coating.Thermospray zinc can obtain the thicker zinc layers of coating, but oxide inclusion in spelter coating is more, easily causes and leakage oozes, be also not suitable as pre-zinc coating.Dip galvanized can obtain thickness coating, and coating is made up of the pure zinc layer on zinc-iron alloy layer and surface, so consider that dip galvanized is conducive to the formation of infiltration layer from the diffusion length of atom; But the investigator of Germany just finds that the hot infiltrate journey of dip galvanized there will be Kinkendal Effect (PeterMaass in the corrosion behavior research carried out the eighties in 20th century, PeterPeissker.Handbookofhot-dipgalvanization, WILEY-VCH, 2011.4), produce infiltration layer vacancy defect, finally cause coating, infiltration layer comes off, visible dip galvanized is also not suitable as pre-zinc coating.
Mechanical zinc-plating also can obtain comparatively thickness coating, as described in Chinese patent ZL93105628.4, can obtain the zinc coating of any thickness in 5 ~ 110 micrometer ranges as required.The zinc powder availability of mechanical zinc-plating process reaches more than 90%, and yield rate is higher than 95%, and the production cost of identical thickness of coating is only 40 ~ 60% of galvanizing.The heat of mechanical galvanizing layer is oozed experiment and is shown, can the infiltration layer of processing machinery zinc coating under certain heat oozes the condition such as temperature, time, but the top layer of steel piece surface mechanical galvanizing layer, in zincizing process, a small amount of oxidation can occur.Given this, the present invention is based on the zinc coating on steel piece surface, a kind of encapsulant that mechanical galvanizing layer heat is oozed sealed environment, promoted mechanical galvanizing layer hot infiltration rate degree, improves the hot quality layer of mechanical galvanizing layer that ensures is proposed, to obtain high-quality, the efficiently hot infiltration layer of mechanical zinc-plating.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, and provide a kind of mechanical zinc-plating steel piece heat to ooze with encapsulant, the zinc coating heat for steel piece surface oozes process.
Mechanical zinc-plating steel piece of the present invention heat is oozed and by the composition of encapsulant and mass percent is: zirconium English powder 40% ~ 70%, zinc oxide 5% ~ 10%, lapis amiridis 10% ~ 30%, ground phosphate rock 5% ~ 15%, quartz sand 10% ~ 15%.
The raw material of encapsulant composition of the present invention is technical grade industrial chemicals general on market.
Encapsulant of the present invention is used for mechanical zinc-plating steel piece and oozes in container filling when heat oozes process and sealing in heat.
When encapsulant of the present invention oozes for mechanical zinc-plating iron and steel heat, encapsulant need by completely isolated for single mechanical zinc-plating steel piece.
Blocking agent agent of the present invention is used for can repeatedly using when mechanical zinc-plating steel piece heat oozes process.
Containing a certain amount of zirconium English powder, lapis amiridis in encapsulant of the present invention composition, encapsulant is had thermal conductivity is large, thermal expansivity is little advantage, can ensure leaving standstill of the hot infiltrate journey of mechanical zinc-plating steel piece.
Containing a certain amount of ground phosphate rock, zinc oxide in encapsulant of the present invention, they have the feature preventing encapsulant caking, improve powder fluidity and compactibility, mobility, density when these can guarantee that encapsulant loads, reduce the zinc oxidational losses on mechanical galvanizing layer top layer.
When encapsulant of the present invention uses: above-mentioned raw materials is weighed by mass percentage and mixes, zincizing case is together packed into afterwards with mechanical zinc-plating steel piece, should ensure during filling that each mechanical zinc-plating steel piece is isolated by above-mentioned encapsulant completely, zincizing container contents fill after through suitable jolt ramming, afterwards zincizing container is added a cover adopt refractory mortar sealing; Then zincizing container is put into process furnace thermal treatment, complete zincizing process.
Beneficial effect of the present invention
(1) quality layer is even, and yield rate is high.
Containing a certain amount of zirconium English powder, lapis amiridis in encapsulant of the present invention composition, encapsulant is had thermal conductivity is large, thermal expansivity is little advantage, can ensure that hot infiltrate journey mechanical zinc-plating steel piece is in static condition, and then ensure the homogeneity of infiltration layer.Ground phosphate rock in encapsulant of the present invention, zinc oxide have the feature preventing encapsulant caking, improve encapsulant powder fluidity and compactibility, contribute to mobility, density when improving encapsulant filling, and then improve the sealing property of encapsulant, avoid heat to ooze the oxidation for the treatment of processes mechanical zinc-plating article surface, improve the yield rate of infiltration layer.
(2) use simply, with low cost.
