Description
【Technical field】
The invention belongs to steel surface chemical heat treatment technology field, and in particular to a kind of powder zincizing agent of fast infiltration rate and
It is applied.
【Background technology】
Outdoor steel structure and fastener, freeway guardrail, bridge, hot-water heating utensil, architectural hardware, automobile, engineering machinery
Deng iron and steel parts, the iron and steel parts used in the engineering such as sintered metal product and chemical industry, ocean, metallurgy, generating, usually
Need corrosion-resistant overcoat.Zinc is most-often used chemical element in steel and iron parts surfacecti proteon：Dip galvanized, thickness typically exists
15-130 μm, member planar has significant difference with corner thickness of coating, and lack of homogeneity is difficult to control；Electro-galvanized layer, thickness is general
At 5-25 μm, plane coating uniformity is good, but the coating of component inside cavity is thin, and sometimes without coating；Thermal spraying zinc layers, thickness
Generally 84-300 μm, also thick 3mm can be reached, thickness evenness is poor, and compactness is low；Sherardised coating, thickness is solely dependent upon zincizing
The technological parameters such as agent, heating-up temperature and soaking time, it is substantially unrelated with the shape of component and position, it is threaded when processing, recessed
During the steel and iron parts of the complicated shape such as groove and endoporus, the thickness of zinc coat is almost identical, and general thickness can be between 10-100 μm
Selection, is accurately controlled near a certain thickness value by adjusting soaking time.
Powder zincizing, is that powder zincizing agent and steel and iron parts are co-located in sealing container, is heated to 400 DEG C or so, makes work
Property zinc atom is internally permeated by the surface of steel and iron parts, and the process of uniform zinc-iron alloy layer is formed on its top layer.Relatively
In other method, the zinc consumption of powder zincizing is low, save raw material；Production process is pollution-free, and working condition is good；Production equipment
Simply, using low with maintenance cost.Powder zincizing has that corrosion resistance is strong, hardness in the zinc-iron alloy layer that steel and iron parts surface is formed
The advantages of high, wear-resistant, scratch resistance, paintability are good.
Burn into corrosion is the natural enemy of ferrous materials.It is lost it is estimated that world's output of steel there are about 1/10th in burn into rust
Erosion.It was verified that under a variety of environment such as marine atmosphere, severe industrial atmosphere, the corrosion resistance of zinc coat is better than galvanizing, electricity
Zinc-plated and stainless steel.Zincizing layer surface Vickers hardness can reach 250-400, and galvanizing, electrolytic zinc-coated steel sheet ironware surface are pure
Zinc, coating Vickers hardness is only 70 or so, therefore zincizing is compared with galvanizing and electrogalvanizing, the surface abrasion resistance of steel and iron parts and anti-
Abrade performance much better.In general, the pre-treatment of zincizing production is only with shot-blasting machine derusting edible vegetable oil, and is removed with cloth bag
Dirt.Powder zincizing technology is oozed for the solid of zinc, is produced without zinc fume, and workpiece enters in closed utensil again with powder zincizing agent
Row infiltration and separation, do not pollute to surrounding environment.According to measuring and calculating, the zinc consumption of hot-galvanized steel ironware ton product is 100 kilograms
Left and right, and powder zincizing is only 30 kilograms or so, only accounts for the 30% of galvanizing.In addition, also corroding this galvanizing without zinc pot
Hard nut to crack.The zinc coat of zincizing product is uniform, and is one-level with the adhesion of paint, can realize to be combined after japanning and prevent
Shield, its corrosion resistance is superior to galvanizing, electrogalvanizing and single zinc coat.The steel product handled through zincizing does not influence material
Mechanical property.The temperature of zincizing processing is lower than galvanizing 100-280 DEG C, and the hydrogen atom that steel matrix is sucked at a temperature of this has spread ease
Go out.Therefore the harm without hydrogen embrittlement in the application, is also avoided that some high intensity parts such as spring mechanics caused by treatment temperature height
The drawbacks of hydraulic performance decline.So, powder zincizing has broad application prospects.
But, the zincizing time that existing powder zincizing agent and its technique for applying need is long；Zinc-iron alloy layer it is corrosion-resistant
Performance can also be improved further；Steel and iron parts surface is bonded with zincizing agent, it is necessary to clear up；Used powder zincizing agent caking, no
It is easy to recycling.
