Technical field:
The present invention relates to the making of diel, be specifically related to the diel that a kind of surface for powder metallurgy formation has ceramic coated composite coating.
Background technology:
Mould has extremely important effect in powder metallurgy industry, the quality of mould directly determines the quality of product.Many workpiece of powder metallurgical technique preparation that use often require just to be no longer to carry out follow-up machining by finished product after once-forming and sintering, so precision and the surface quality of mould had very high requirement.In the process that the manufacturing of mould is used, wearing and tearing often can appear in mould, the phenomenons such as dimension overproof in fatigue failure, generation cut, groove and load mould and processing, causes whole mould to use.The inefficacy of mould not only affects the quality of product but also increases production cost, and frequently more mold exchange more can cause production declining, brings huge economic loss to enterprise.On the other hand, because the kind of mould is many, standard component is few, and the manufacturing cycle is long, processing charges high (especially accurate complicated die or large mold), and enterprise is often because of the inefficacy reduce or stop production of mould.Therefore adopting suitable method to improve die quality, extend the mold use life-span, reduce costs, economize on resources, is the important topic that current Powder Metallurgy Industry faces.
In prior art, the diel material that is used for powder metallurgy formation is mainly two kinds, hard alloy steel and wolfram steel.Hard alloy steel low price, easy to process, the high energy of its hardness reaches the HRC60 left and right after suitable heat treatment, can satisfy the stamping of general parts.But the parts high to required precision, because wearing and tearing are larger, service life is shorter, as the automotive engine valves diel, uses hard alloy steel, only has 1-2 ten thousand times its service life.The wolfram steel material hardness is higher, and more than reaching HRC70, its anti-wear performance is compared with carbide alloy and improved a lot.During used as the engine valve mould, generally can reach 5-6 ten thousand times service life.But the wolfram steel material is generally high temperature sintering and forms, complex manufacturing technology, and cost is very high, has limited its application in diel.
Summary of the invention:
The object of the invention is to, for deficiency of the prior art, the shaping and punching mould that provides a kind of surface that utilizes the supersonic spray coating technology to obtain to have wear-resistant coating, it has the performances such as anti-wear performance is good, case hardness is high, serviceability temperature is high, can satisfy various mold use requirements.
Technical scheme of the present invention is as follows:
Shaping and punching mould with wear-resistant coating of the present invention, include die matrix, it is characterized in that, the ceramic composite coating that the two phase structure that use supersonic spray coating (HVOF) technology prepares is arranged on the surface of this matrix, wherein one is tungsten carbide (WC) or chromium carbide (Cr by micron powder mutually
3C
2) ceramic phase that consists of, another is the alloy phase that the nickel-base alloy by micron powder consists of mutually, nickel-base alloy is embedded in ceramic phase; Wherein, the mass ratio of ceramic phase and alloy phase is 1:(0.1-1), described ceramic composite coating thickness is the 100-500 micron.Described Co-based alloy powder is comprised of elements such as nickel (Ni), chromium (Cr), molybdenum (Mo), iron (Fe), aluminium (Al), titanium (Ti), boron (B), silicon (Si), the nickel-base alloy F102(Ni16Cr4B4Si that for example buys on market, hardness is HRc 60) powder or F102Fe(Ni16Cr4B4Si15Fe, hardness is HRc 60) powder, F103(Ni10Cr1.5B3Si, hardness is HRc 60) powder etc.
Shaping and punching mould with wear-resistant coating of the present invention, the lip-deep ceramic composite coating of its die matrix uses the preparation of supersonic spray coating (HVOF) technology.The HVOF coating technology can be with the tungsten carbide in supersonic flame or chromium carbide ceramics powder and Co-based alloy powder melting and the sintering working surface at mould, and under the internal compressive stress in coating, nickel-base alloy embeds and forms the two-phase composite coating in carbide.Wherein ceramic phase chromium carbide or tungsten carbide can provide high case hardness (1000-1200 HV) and high adhesive strength, and nickel-base alloy makes coating form firmly with die ontology and is combined.
Described ceramic composite coating not only effectively improves the resistance to blocking energy, also has outstanding wearability, and its wear intensity reduces 70%-80% than the hard alloy steel that uses in prior art, than the low 20-30% of wolfram steel.Therefore this ceramic composite coating can extend the mold use life-span greatly, satisfies various mold use requirements, can also satisfy the high requirement of shaping and punching Product Precision stability, is conducive to improve the quality of shaping and punching product; And by contrast, it is comparatively simple that it also has manufacture craft, lower-cost advantage.
