Detailed description of the invention
Embodiments of the present invention are described in detail, thereby to the present invention how application technology hands below in conjunction with embodiment
Section solves technical problem and reaches the process that realizes of technology effect and can fully understand and implement according to this.
The present invention provides a kind of tungsten carbide Fe-based self-fluxing alloy resurfacing welding material, described resurfacing welding material be Fe-based self-fluxing alloy and
The mixture of the tungsten carbide of 20%-30% weight portion, the granularity of tungsten carbide is 100-200 mesh, and overlay cladding microscopic structure is by polygonal
Shape tungsten carbide and a small amount of eutectic composition.
Wherein, the weight portion of tungsten-carbide powder is the weight relative to Fe-based self-fluxing alloy, adds WC and can make metal material
Material case hardness, wearability improve, and can be applicable to hardness and wearability and require high occasion, but the too high meeting of tungsten carbide content
Causing overlay cladding and mother metal i.e. Fe314 metallurgical binding bad, therefore tungsten carbide consumption selects 20%-30%.The granularity of tungsten carbide
OK range, the excessive or too small wearability that all can reduce, the therefore granularity selection 100-200 mesh of tungsten carbide need to be selected.
Preferably, resurfacing welding material is 2-3mm at matrix surface overlay cladding thickness.Wherein, thickness is the least causes overlay cladding to be subject to
The impact of mother metal dilution rate is big, reduces performance, and thickness causes the most greatly not weld penetration or overlay cladding bad with mother metal metallurgical binding, because of
This thickness selects 2-3mm.

3mm, remaining condition is same as in Example 1.
The sample of heap postwelding is polished, polishing, then the nital corrosion sample with 4%, vertical in XJL-024 type
Overlay cladding microscopic structure is observed on metallurgical microscope.Utilize the Rockwell hardness of HR150-A type Rockwell hardness machine test overlay cladding, often
Three numerical value surveyed by individual sample, then calculate the meansigma methods Rockwell hardness as this sample.Disc type abrasive test is sold at ML-100
Carry out abrasive grain wear test on machine, the sample before and after abrasion is placed on electronic balance weighing, calculates wear extent.
Test result:
(1) overlay cladding Metallographic Analysis
Fig. 1 is the Fe314 overlay cladding microscopic structure of comparative example 1 coating layer thickness 2mm, and it is organized as primary austenite and is added few
Amount eutectic, is a kind of hypoeutectic structure；Fig. 2 is the Fe314 surfacing layer of comparative example 2 coating layer thickness 3mm, and it is typical mistake
Eutectic structure, has a small amount of alloyed cementite (white strip phase) on a large amount of eutectic structure matrixes, and alloyed cementite should
For (Fe, Cr)3C, remaining tissue should be the eutectic of Various Complex compound, such as carbide and boride etc., the most relatively,
Fig. 2 surfacing layer is similar with Fe314, is still high-chromium alloy cast-iron type, and this increases heap mainly due to along with coating layer thickness
The reason that layer tissue is reduced by mother metal diluting effect.Fig. 3 is embodiment 1 coating layer thickness 3mm, the overlay cladding group containing 20%WC
Knitting, have a small amount of nascent solid solution dendrite and a large amount of eutectic structure in tissue, this explanation dilution rate is less, overlay cladding composition close to
The primitive component of self-fluxing alloy, may melt due to the highest WC of WC content again in weld deposit process；Fig. 4 is that embodiment 2 is coated with
Layer thickness 3mm, the surfacing layer containing 30%WC, this tissue is the most typical, is by polygon carbide (tungsten carbide) and a small amount of
Eutectic composition, according to relevant information analysis, polygonal for tungsten carbide, strip for alloyed cementite, and these compounds
It is to separate out under solid phase and grow up.
(2) surfacing hardness analysis
Surfacing hardness value when table 3 is different coating thickness and different WC content, from table 3 it is observed that work as alloyed powder
End increases with the increase of coating layer thickness without the hardness of overlay surface during WC, it can be seen that work as and be coated with from metallograph
When layer thickness is 3mm, surfacing layer is hypereutectic tissue, has (Fe, Cr) in tissue3C-type carbide and austenite and carbon boron
The eutectic structure of compound, therefore when coating layer thickness is 3mm, hardness is higher；When coating layer thickness is that 3mm is constant, Fe314 adds
When entering WC, the hardness of overlay surface increases along with the increase of WC content, has part WC particle in built-up welding when WC content is less
Shi Fasheng melts, and has a large amount of eutectic in its metallographic structure, and therefore hardness number is the highest.When WC content reaches 30%, by gold
Phase constitution it can be seen that there is a large amount of WC particle in Zu Zhi, the dispersion-strengthened action of these hard particles, make alloy welding deposit layer have
Higher wearability, red hardness and non-oxidizability, therefore when WC content is 30%, surfacing hardness value is 65.7HRC to the maximum.
Table 3 surfacing hardness
(3) overlay cladding Analysis on Wear
The abrasion value of overlay cladding when table 4 is different coating thickness and different WC content, generally, material is the hardest,
Wearability is the best, from table it can also be seen that, when in alloy powder without WC, during coating layer thickness 3mm, hardness number is the highest, wear extent
Minimum, when coating layer thickness 3mm is constant, when WC content reaches 30%, hardness number is the highest, and wear extent is minimum.WC is superhard hard
Matter phase, the hard phase WC in overlay cladding can make the hardness of sample overlay surface increase substantially, and wear extent drastically declines.
Table 4 overlay cladding wear extent
In sum, when coating layer thickness is 3mm, and WC content reaches 30%, and overlay cladding microscopic structure is by polygon carbide
(tungsten carbide) and a small amount of eutectic composition, hardness number reaches to be up to 65.7HRC, the minimum 11.7mg of wear extent.
The present invention adds the carbonization with characteristics such as high rigidity, high-wearing feature, high-melting-points in fe-based self-fluxing alloy powder
Tungsten, as resurfacing welding material, utilizes carbon-dioxide arc welding to carry out built-up welding as thermal source, overcomes existing resurfacing welding material case hardness
With the problem worn no resistance, it is thus achieved that high case hardness and wearability.
Described above illustrate and describes some preferred embodiments of invention, but as previously mentioned, it should be understood that invention is not
It is confined to form disclosed herein, is not to be taken as the eliminating to other embodiments, and can be used for other combinations various, amendment
And environment, and can be carried out by above-mentioned teaching or the technology of association area or knowledge in invention contemplated scope described herein
Change.And the change that those skilled in the art are carried out and change are without departing from the spirit and scope of invention, the most all should weigh appended by invention
In the protection domain that profit requires.
