Description
Technical field
The invention belongs to the component of machine service technique, relate generally to agricultural machinery and implement and touch native parts plasma surfacing material and overlaying process.
Background technology
In the farm machinery parts, the wearing and tearing of soil contact component mainly belong to abrasive wear, and because of its work under bad environment, the abrasion and corrosion amount is huge.The parts of the broken soil such as the ploughshare in Agricultural Machine Parts, blade, deep soil loosing shovel, plough, For Rotary Tiller Blade, its wearing and tearing are subject to the strong wear of the hard abrasive such as stone, sand grains while being mainly blade incision soil and broken soil block.According to investigations, when carrying out the large tracts of land Subsoiler, the subsoiling spear working life of domestic production is only 30～40h, and the spear cost of preparation high-wearing feature is higher.Because the plasma surfacing arc column is stable, temperature is high, heat is concentrated, the standard parameter adjustability is good, molten bath is tranquil, can control collective's metal fusion penetration, reduce dilution ratio, the advantage such as easily be automated, the common surface property that improves in this way material both at home and abroad at present.But, touch particular job characteristics of native parts for above-mentioned farm machinery, the built-up welding coating abrasion performance that existing plasma surfacing alloy powder and overlaying method are prepared is difficult to meet the work requirements that agricultural machinery touches native parts, and the agricultural machinery worker catchs at a kind of workable and lower-cost alloy powder and overlaying method for preparing the tactile native parts plasma surfacing wearing layer of agricultural machinery and implement.
Summary of the invention
Purpose of the present invention is exactly the problem existed for above-mentioned prior art, touch native parts real work characteristics in conjunction with agricultural machinery and implement, research and develop a kind of new agricultural machinery and implement and touch native wear resistant alloy powders and overlaying method for the parts plasma surfacing, reach and increase substantially anti-wear performance, extend the purpose that agricultural machinery and implement touch native parts service life, reduce the agricultural production operating cost.
The object of the present invention is achieved like this:
A kind of agricultural machinery and implement touch native parts plasma surfacing wear resistant alloy powders, described wear resistant alloy powders is comprised of by Different Weight percentage following composition: 0.5-5.0% C, 0.10-0.75% Pb, 15.0-20.0% Cr, 0.20-1.0% Ti, 0.10-0.50% W, 0.20-1.0% Mn, 0.2-0.4% Al, 0.3-0.6% Ni, surplus is Fe.
A kind of agricultural machinery and implement touch native parts plasma surfacing method, and when the plasma-arc built-up welding, the magnetic field magnetic line of electromagnetic induction device alternately is horizontally through the plasma arc axis of plasma surfacing rifle.
Agricultural machinery and implement touch native parts plasma surfacing device and comprise the plasma surfacing rifle, on base plate, be positioned at equipped crystallization mangneto vibrator below the plasma surfacing rifle, on base plate, be positioned at crystallization mangneto vibrator left and right side position place respectively setting height(from bottom) regulate crane, the electromagnet of cover distribution circle is fitted in respectively the height of left and right side and regulates on crane, and wire is communicated with coil with supply unit.
The magnetic induction intensity of electromagnetic induction device is 100-1000GS, and frequency range is 1-30Hz.
The vibration frequency of described crystallization mangneto vibrator is 10-70Hz.
In the present invention, plasma surfacing reaches requirement with the C composition carbide hard phase amount in wear resistant alloy powders, has improved toughness of material; The Pb composition has deoxidation; The Cr composition guarantees to obtain take the Me7C3 type as main carbide and hard phase quantity, makes C partly dissolve in austenite, plays and improves the quenching degree effect, and Ti improves the strength of materials; W is carbide, add on a small quantity can be in alloy disperse go out the alloy carbide of high rigidity; Mn has deoxidation and controls the illeffects of sulphur, phosphorus; Al is inovulant, promotes forming core, and crystallization crystal grain is little.The present invention's electromagnetic action device used can realize forming the build-up wear-resistant coating under the transverse magnetic field effect.When the magnetic line of force of transverse magnetic field alternately is horizontally through arc axis, in the electromagnetic force butt welded seam, liquid metal plays stirring action, liquid metal comes repercussion the crystal just formed, the crystal growth is suppressed, thereby obtain the tissue that nucleus increases, crystallization direction is not obvious, crystal grain is tiny, strengthen the built-up welding coating abrasion performance.The crystallization mangneto device that shakes makes workpiece produce the vibration of setpoint frequency when plasma surfacing, promotes grain refinement, improves coating performance.Formula of the present invention is reasonable, and method and apparatus is simple, and built-up welding is effective, and anti-wear performance is high, and long service life has reduced the agricultural production operating cost.
