Abstract
The invention relates to the field of blades and especially to a wear resistant blade. The wear resistant blade is characterized in that a wearing layer is fixed on the inner wall of a blade body. Since vacuum fusion covering is employed for extrusion coating of the self-fluxing alloy powder on the external surface of the blade body, metallurgical bonding between the alloy powder and a cylinder barrel material is realized, and the blade with high wear resistance and high corrosion resistance is developed.

The invention has the beneficial effects as follows, due to the self-fluxing alloyed powder of high-wearing feature, high corrosion resistance being arranged at the even squeezing and coating of blade body inwall place's employing vacuum melting and coating technique, make alloy powder and cylinder barrel material realize metallurgical binding, develop have high-wearing feature, the blade of high corrosion resistance.
Description of drawings
The present invention is further described below in conjunction with the embodiment accompanying drawing.
Fig. 1 is the structural representation of this wear resisting vane;
Fig. 2 is the flow chart that the vacuum melting and coating process increases wearing layer.
In figure: 1, blade body; 2, wearing layer.
The specific embodiment
This wear resisting vane is to increase wearing layer 2 by the vacuum melting and coating process at the outer surface of blade body 1, see Fig. 1, wearing layer thickness is 0.01～2mm, wearing layer 2 is to be mixed by alloy powder and adhesive, wherein alloy powder is the self-fluxing alloyed powder of high-wearing feature, high corrosion resistance, adopt the vacuum melting and coating technique, make alloy powder and blade surface realize metallurgical binding, then form the blade with high-wearing feature, high corrosion resistance through other process.
As shown in the flow chart that the vacuum melting and coating process of Fig. 2 increases wearing layer, the vanes of this high-wearing feature, high corrosion resistance is crossed following method step and is processed:
At first step 1 carries out pretreatment to blade, and pretreatment mainly comprises blade dimensions reservation and sharp processing, and surface clean, degreasing, decontamination, rust cleaning can be adopted acid cleaning process in case of necessity;
Step 2, modulation is mixed by alloy powder and adhesive from the dissolubility alloy powder from the dissolubility alloy powder, and the rosin of the turpentine oil dissolving 25% with 75% is as binding agent, be modulated into the pasty state slip with 6% rosin binding agent and 94% alloy powder again, above-mentionedly all be weight percentage;
Above-mentioned alloy powder is a kind of in nickel-base alloy (Ni-B-Si and Ni-Cr-B-Si) or cobalt-base alloys (Co-Cr-W-Ni-B-Si) or ferrous alloy (Fe-Ni-B-Si and Fe-Cr-Ni-B-Si), boron and silicon that they all contain can reduce fusing point, improve hardness, deoxidation slag making voluntarily;
Apply in step 3, cylinder body, the slip that modulates is coated to the inner surface of cylinder body;
Type is dried, repaiied to step 4, puts into 80～100 ℃ of baking ovens after the cylinder body after applying is dried in the shade and be incubated 2～3 hours, so that turpentine oil volatile takes out after slow cooling, revises profile;
Step 5, the vacuum cladding, vacuum sintering is clinkering in the molybdenum wire furnace of 10Pa in vacuum, determine heating-up temperature according to alloying component, (Ni-Cr-B-Si) is 1050～1100 ℃ as nickel-base alloy, during insulation, firing rate should slowly, prevent the too fast coating cracking that causes of organic matter volatilization;
Step 6, fine finishining after cladding is carried out right boring, hone or grinding to coating, to satisfy the specification requirement of cylinder barrel size and form and position tolerance, surface roughness;
Step 7, check;
Step 8, warehouse-in.
The process characteristic of vacuum cladding:
Compactness is high: the temperature of vacuum sintering is between the liquidus curve and solidus of coating material, and coating alloy is in liquid, solid two-phase coexistent state, and vacuum sintering coating mesopore rate is relevant with liquid content.When the liquid phase mass fraction was 20%～30%, what obtain was the coating of porous, can obtain the coating of continuous sealing when the liquid phase mass fraction surpasses 60%.Control the ratio of liquid phase, can prepare the minimum dense coating of porosity or anti-attrition micro porous coating.
Dilution rate is low: because firing rate is fast, temperature retention time is short, and heating-up temperature is lower than the fusing point of mother metal, and therefore, mother metal element (being mainly iron) is less to " dilution " of coating, and coating composition changes little, even tissue, and hardness and wearability are high.
Thickness is controlled: coating layer thickness accurately can be controlled at several microns to several millimeters, and the enforcement of vacuum sintering technique is not subjected to the impact of workpiece shape, structure or position complexity, even locate in blind hole, inside groove etc., also can forms the coating of uniformity.
