Hardness material increases the wear resistance of parts of slurry pump

    Experimental results show that the impact toughness of the material and its erosion is no clear correlation between the abrasion wear resistance. Only guarantee toughness parts of slurry pump (impeller, jacket, volute, guard) will not fracture during use, mainly in the impact wear, cracks can prevent an impact. Removal mechanism slurry erosion material under the action of deformation furrows piercing, micro-cutting and solid particles, so that with increasing hardness of the material to resist deformation, cutting, and enhanced ability to penetrate the quantity of material removal reduced wear resistance.

Therefore, under the conditions of erosion, abrasion hardness of the material depends on the material, improving the strength and toughness of materials against corrosion erosion is also beneficial.
