Description
Technical field
The invention belongs to laser melting and coating technique field, in particular to a kind of laser manufactures impact-resistant abrasion-proof alloy powder.
Background technique
Laser fabrication technology history is not long, but is developed so far from its birth, in aerospace field, garage
There is a large amount of engineer application in the fields such as industry, metallurgy, petrochemical industry, electric power large rotor, but do not have the powder specifically for laser manufacture
End.The technical advantage of laser manufacture is the laser using high energy beam, utilizes powder quickly to be formed in matrix surface complete with matrix
Different alloy-layers, while having a certain amount of basic material and being diluted in alloy-layer, i.e., alloy composition of layer is designed to powder
Divide and generates deviation, and existing a large amount of powder design does not all consider the diluting effect of matrix.
Now with the rapid growth of industrial products steel, coal, cement output, raw material, the broken of finished product, grinding work
Consume a large amount of wear-resistant material.Largely the operating condition of the jaw tup of component such as crushers, ball grinding machine lining board, abrading-ball etc. is all
Impact and abrasion compound action, and shock resistance decline can be directly resulted in by improving wearability, seriously affect workpiece uses the longevity
Life, this is implacable contradiction under impact wear operating condition, while using traditional preparation method prepare impact-resistant abrasion-proof layer when
There is the net distributions of the segregation of tissue and hard phase, can all deteriorate shock resistance.Laser manufacture quickly solidification, tissue are thin
The small uniformly granular distribution of hard phase simultaneously, so that the alloy-layer of laser manufacture has better Impact wear resistance.
Summary of the invention
According to above content, the invention mainly includes researching and developing, a kind of shock resistance meeting impact wear duty requirements is resistance to
Alloy material is ground, it can be full in carbon steel, low-alloy steel, high-alloy steel matrix surface manufacture cladding layer by laser melting and coating technique
Abrasion resistance properties demand of foot under the conditions of impact.
A kind of impact-resistant abrasion-proof material for laser manufacture, is grouped as by following mass percent group: C:2.9-3.8%,
Cr:15-23%, Si:1.00-1.30%, Ni:0.2-0.95%, Mn:0.9-1.5%, W:2-5.5%: V:14-21%, B:0.8-
1.8%, Nb:5.50-10%, Y:0.8-2.3%, surplus are Fe and inevitable impurity.
The characteristics of this alloy powder, is to fully consider that matrix prepares alloy-layer to laser using ferrous alloy as matrix
The influence of energy breaks through the proportion rule of traditional alloy design, using the ability of the superpower capture carbon of niobium and vanadium, inside alloy-layer
Form a large amount of abrasion-resistive hard particle；The chromium of certain content can be in free state in alloy-layer simultaneously, have alloy-layer
Tissue has a certain amount of retained austenite while good corrosion resisting property, can meet rushing with corrosive medium fluid simultaneously
It hits and washes away.
A large amount of experiment has been carried out in the research process of the powder, has carried out multiple groups reality for impact-resistant abrasion-proof performance demand
The content proportion for having first verified that carbon and vanadium is tested, discovery obtains alloy-layer when carrying out material composition design using vanadium/carbon ≈ 3
Hardness less than HRC50, and after being heat-treated, hardness is further decreased, find that there are bases through composition detection and design ingredient comparison
The dilution of body and the scaling loss of carbon cause laser to prepare the deviations of alloy-layer and powdered ingredients.It is found into multiple groups experimental verification is crossed
The ratio excellent of vanadium carbon of the invention, this become the impact-resistant abrasion-proof material design basis, on this basis into
The perfect experiment of powder property of having gone.The collective effect of niobium and vanadium can further refine crystal grain and reduce grain size, promote crystal grain
Refinement while refined the sizes of abrasion resistant particles, this has very big raising, while the carbide of niobium to shock resistance
It can be distributed in crystal boundary, certain pinning effect is woven with to group, the intensity of alloy-layer parent phase can be improved, ensure that alloy-layer is provided simultaneously with
Good wearability and impact resistance.Design of material will combine vanadium/carbon, vanadium/niobium and niobium/carbon ratio in the invention, warp
Test data is verified as vanadium: niobium: carbon ≈ 10:5:2.So the design of niobium element content is also the pass that the design of material needs to optimize
Key factor, content of niobium are less than 5.5%, and unobvious to the thinning effect of crystal grain, content of niobium is greater than 10%, and the carbide of niobium has obviously
Clustering phenomena destroy laser cladding layer shock resistance, while extra niobium can with iron formed unstable compound it is further
The shock resistance of deteriorated tissue, so to be designed as 5.5-10% best for the content of niobium.It is good that the addition of chromium allows alloy-layer to have
Corrosion resistance, while residual chromium is remarkably improved the content of wearability and retained austenite to the solution strengthening of matrix, it is preferably full
The demand of foot impact operating condition.Ferrous alloy is generally difficult to take into account wearability and obdurability, increases carbon content to increase wearability
When with alloy content, the toughness that will lead to the agglomeration deterioration alloy of alloy carbide causes shock resistance to decline.This hair
The bright collective effect using vanadium niobium and optimize its ratio, so that the ferrous alloy of laser manufacture obtains of a large amount of Dispersed precipitates
Grain does not deteriorate toughness, so that ferrous alloy has simultaneously because the good collocation of vanadium niobium carbon ensure that particle dispersion distributional pattern
Good Impact wear resistance.
