Abstract
The invention discloses a kind of no hydrogen embrittlement and the powder zincizing steel pieces of surface damage, include the following steps and are made: (1) steel piece of powder zincizing agent and desire zincizing being packed into the ceramic-lined cylinder of drum-type heating furnace, sealed；(2) drum-type heating furnace rotates, and is warming up to 330-345 DEG C；(3) temperature is controlled, microwave is increased, drum-type heating furnace revolving speed is risen into 60r/min from 1r/min, then reduction of speed is to 1r/min, such Circularly liftable 9-12min；(4) then stop microwave, be changed to increase ultrasonic wave, drum-type heating furnace revolving speed is risen into 70r/min from 1r/min, then reduction of speed after such Circularly liftable 5-8min, is slowly cooled to room temperature, blowing out, steel piece is made to 1r/min.Steel piece of the invention is without hydrogen embrittlement and surface damage, and zincizing technical process does not have environmental pollution, and utilization rate of zinc is high, can effectively save raw material.
Description
[technical field]
The invention belongs to steel surface chemical heat treatment technology fields, and in particular to the powder of a kind of no hydrogen embrittlement and surface damage
Last zincizing steel piece.
[background technique]
Outdoor steel structure and fastener, freeway guardrail, bridge, hot-water heating utensil, architectural hardware, automobile, engineering machinery
Equal iron and steel parts, iron and steel parts used in the engineerings such as sintered metal product and chemical industry, ocean, metallurgy, power generation, usually
Need corrosion-resistant protective layer.Zinc is chemical element most-often used in steel and iron parts surfacecti proteon: dip galvanized, and thickness generally exists
15-130 μm, member planar and corner thickness of coating have significant difference, and uniformity is poor, are difficult to control；Electro-galvanized layer, thickness are 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, thick 3mm can also be reached, the thickness uniformity is poor, and compactness is low；Sherardised coating, thickness are solely dependent upon zincizing
The technological parameters such as agent, heating temperature and soaking time, it is substantially unrelated with the shape of component and position, when processing is with screw thread, recessed
When the steel and iron parts of the complicated shapes such as slot and inner hole, the thickness of zinc coat is almost the same, 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 to live
Property zinc atom is internally permeated by the surface of steel and iron parts, forms the process of uniform zinc-iron alloy layer on its surface layer.Relatively
In other methods, the zinc consumption of powder zincizing is low, saves raw material；Production process is pollution-free, and working condition is good；Production equipment
Simply, using low with maintenance cost.The zinc-iron alloy layer that powder zincizing is formed on steel and iron parts surface has that corrosion resistance is strong, hardness
The advantages that high, wear-resistant, scratch resistance, paintability are good.
Burn into corrosion is the natural enemy of steel material.It is estimated that there are about 1/10th losses in burn into rust for world's output of steel
Erosion.It was verified that the corrosion resistance of zinc coat is better than hot galvanizing, electricity under a variety of environment such as marine atmosphere, severe industrial atmosphere
Zinc-plated and stainless steel.Zincizing layer surface Vickers hardness can achieve 250-400, and hot galvanizing, electrolytic zinc-coated steel sheet ironware surface are pure
Zinc, coating Vickers hardness are only 70 or so, therefore zincizing is compared with hot galvanizing and electrogalvanizing, the surface abrasion resistance of steel and iron parts and anti-
It is much better to abrade performance.Under normal circumstances, 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 that the solid of zinc seeps, and is generated without zinc fume, workpiece and powder zincizing agent again in closed utensil into
Row infiltration and separation, do not pollute ambient enviroment.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 hot galvanizing.In addition, also corroding this hot galvanizing without zinc pot
Hard nut to crack.The zinc coat of zincizing product is uniform, and is level-one with the binding force of paint, is able to achieve after japanning compound anti-
Shield, corrosion resistance are superior to hot galvanizing, electrogalvanizing and single zinc coat.The steel product handled through zincizing does not influence material
Mechanical property.The temperature of zincizing processing is 100-280 DEG C lower than hot galvanizing, and the hydrogen atom that steel matrix is sucked at a temperature of this has spread ease
Out.Therefore the not harm of hydrogen embrittlement in the application is also avoided that some high-intensitive parts such as spring because of mechanics caused by treatment temperature height
The drawbacks of performance declines.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 further increase；Steel and iron parts surface is bonded with zincizing agent, needs to clear up；Used powder zincizing agent agglomeration, no
