Abstract
The utility model discloses an abrasion-resistant water turbine blade. A modified wolfram carbide (WC) abrasion-resistant coating 2 is thermally coated and covered on the back of a blade 1. By adjusting the ratio of alloy element components, the WC particle size ratio and the like, the material has good thermal coating process performance, so that decarburization decomposition of WC under the thermal coating condition can be effectively reduced, and growth and performance degradation of the nano WC particles under the thermal coating condition are inhibited. The coating has high bonding strength with matrix, high surface hardness and low porosity.
Description
Technical field
The utility model relates to a kind of hydraulic machinery flow passage components anti-abrasion coating, and is particularly a kind of to being applied to operate in the sand content turbine blade of the anti-abrasion of characteristic greatly.
Background technique
Sand erosion under the silt carrying flow effect and cavitation wear double action make water turbine overflowing component badly damaged; This moment, sand erosion proportion was higher relatively; The increase of wearing depth can impel the hole worsening condition again; Form vicious circle, the serious position of Francis turbine abrasion is vacuum side of blade outlet limit near the crown runner between ring place, the blade down successively, encircle inner and outer surface etc. down.
Material property is to the effect of anti-abrasion: material surface hardness is high, and anti-cavitation corrosion performance is good more; Work-hardening exponent is high, and anti-cavitation corrosion performance is good more; Crystallite dimension is more little, and anti-cavitation corrosion performance is good more; Anti-fatigue performance is good more, and anti-cavitation corrosion performance is good more; Surface finishment is high, and anti-cavitation corrosion performance is high more; In the limit of being heated, the good anti-more cavitation corrosion ability of elasticity is strong more.
Conventional surface applies because of coating and high base strength, surface hardness is not high, toughness is not enough and porosity ratio is big, the anti-erosion performance index error.
The model utility content
The purpose of the utility model provides the turbine blade of a kind of anti-cavitation corrosion, anti-abrasion that polishing machine is good.
Turbine blade nano modification Tungsten carbite anti-abrasion coating.
The technological scheme of the utility model is: a kind of turbine blade of anti-abrasion, it is coated with the modified carbonize tungsten anti-abrasion coating that thickness is 0.2mm in the vacuum side of blade thermal spraying.
Described blade matrix is 0Cr13Ni4Mo.
The beneficial effect of the utility model is: this material surface abrasion-resistance is higher more than 70 times than 0Cr13Ni4Mo, compares with existing nano WC-Co material, has bigger adhesive strength, surface hardness and littler porosity ratio.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Embodiment is as shown in Figure 1, a kind of turbine blade of anti-abrasion, and the back side thermal spraying of its blade 1 is coated with modified carbonize tungsten anti-abrasion coating 2.
The utility model makes this material have good hot-spraying technique performance through regulating alloy element component proportioning, wc grain size proportioning etc.; Can effectively reduce the decarburization of WC under the thermal spraying condition and decompose, suppress nanometer WC particle growing up under the thermal spraying condition, performance degradation.Make coating and matrix that higher binding strength, surface hardness and less porosity ratio arranged.
Claims (2)
1. the turbine blade of an anti-abrasion, it is characterized in that: the back side thermal spraying of its blade (1) is coated with the modified carbonize tungsten anti-abrasion coating (2) that thickness is 0.2mm.
2. the turbine blade of a kind of anti-abrasion according to claim 1, it is characterized in that: its blade (1) matrix is 0Cr13Ni4Mo.
