Abstract
The invention provides boron-containing laser-cladding alloy powder which is a powder composition prepared from matrix alloy powder, carbide hard particles and a binder in according to the following matching ratio: 50-90% of matrix alloy powder, 1-40% of WC and TiC mixed powder, and 1-10% of the binder.
Description
Technical field
The invention belongs to cladding technical field of alloy, relate to a kind of boracic cladding alloy powder.
Background technology
In the daily life and industrial production in modern times, the attrition and attack of metallic substance appears in every field, one of the two large major ways destroying component of machine, engineering component, corrosion will cause a large amount of consumption of mechanical component, and wearing and tearing are then one of major reasons causing mechanical component to lose efficacy.They, while a large amount of metallic substance of loss, waste ample resources, occupy very large proportion in financial loss.
The state of laser melting coating layer material generally has Powdered, thread, paste etc.In addition also can using sheet metal, sintered metal product, steel band and welding rod etc. as cladding material, wherein powdered alloy is most widely used in laser melting and coating technique.
Matrix material is a kind of novel surface strengthening engineering materials, and metal and metal, metal and pottery, pottery and pottery etc., the range of choice of the collocation between powdered alloy and between powdered alloy and pottery is very extensive.Recent domestic has carried out in the powdered alloy system of above-mentioned laser melting coating, add certain content various dystectic carbide, nitride, boride and ceramic oxide particle for this reason, make the even pure ceramic coating of cermet composite coating, to improve the wear resistance of cladding layer.
Although adopt matrix material to carry out laser melting coating can prepare high performance composite coating, but to be domesticly mostly still in the research in laboratory at present, and its preparation technology adopts the WC powder of nickel-based self-fluxing alloy with certain content to mix in laboratory, then saturated turps or homemade organic binder bond is added, furnishing slip or paste, precoating is overlying on workpiece, then carries out laser melting coating or sintering.Its hard particles added is comparatively large, density is different from matrix metal, and the distribution of particle in cladding layer is often uneven, usually presents Gradient distribution; Added particulate material and the wettability of matrix, stability, the coefficient of expansion and chemical reactivity etc. all cause the ununiformity of the microstructure and property of cladding layer.And prepared combination powder differs greatly due to each constituent element proportion, thus easily produces segregation in storage, transport and use procedure.Cannot commercialization supply be carried out, commercially there is not yet the merchandise sales of particle reinforce laser melting coating special powder at present.For above-mentioned reasons, there is not yet laser melting coating special combination powder so far, thus constrain the application of laser melting coating on high abrasion operating mode field.
Summary of the invention
The object of the invention is to avoid above-mentioned deficiency of the prior art, develop and a kind ofly can meet a kind of boracic cladding alloy powder required under engineering machinery serious abrasive wear working condition.
For achieving the above object, the present invention can be realized by the scheme of the design of following basic chemical composition and interpolation carbide particle:
A kind of boracic cladding alloy powder provided by the present invention is made up of matrix alloy powder and carbide hard particles and binding agent, its proportioning is: 50 ~ 90% matrix alloy powder, the mixture powder of WC and TiC of 1 ~ 40%, the binding agent of 1 ~ 10% is prepared into combination powder; Wherein the chemical composition of matrix alloy and mass percent thereof are;
0.5 ~ 0.9%C, 2.0 ~ 4%Si, 2 ~ 5%Ni, 18 ~ 26%Cr, 8 ~ 11%Cu, 6 ~ 8%W, 5 ~ 8%Mo, < 15%Fe, 0.1 ~ 0.4%Ce, 0.2 ~ 0.3%La
2o
3, B surplus and inevitable impurity element.
