Embodiment Construction

[0011] The present invention will be further described below in conjunction with the examples, but it does not represent the only embodiment of the present invention.

[0012] Coarsening of zirconium corundum ceramic balls: choose zirconium corundum ceramic balls, the hardness is 2400HV, and the diameter of zirconium corundum ceramic balls is 5-10mm. Chemical Composition: Al 2 o 3 76.16%; ZrO 2 20.35%; SiO 2 0.6%;TiO 2 1.69%, the ball diameter is 5-10mm, put the ceramic ball into the hydrofluoric acid solution (VHF: VH 2 O=1:1), stir for 30 minutes to coarsen, take out the ceramic balls, pre-rinse with clean water, put them into an ultrasonic cleaner for final rinse, and take out the ceramic balls.

[0013] Paint preparation: Manually crush vanadium-iron blocks into 2-3mm particle size, put them into the ceramic tank of the ball mill, add the same amount of ceramic balls, start the ball mill, and process for 8 hours to make vanadium-iron powder. Mix ferrovanadium pow...

Abstract

The invention discloses a manufacturing method for a zirconia corundum ceramic ball-low alloy steel composite material and aims to provide a manufacturing method, with the advantages of no increase of product cost and substantial improvement of the service life of a product, for a composite wear-resistant material. The method comprises the following steps: 1) mixing vanadium iron powder, a soluble glass binder and water according to a mass ratio of 9-11: 1: 1 to prepare a coating; 2) placing zirconia corundum ceramic balls in hydrofluoric acid liquid for roughening; 3) placing the zirconia corundum ceramic balls roughened in step 2) in grids of a steel wire mesh, with an interval between two ceramic balls being in a range of 5 to 8 mm, covering the arranged ceramic balls with another steel wire mesh and fixing the two steel wire meshes; 4) immersing the steel wire meshes fixed with the ceramic balls in step 3) in the coating, then taking out the steel wire meshes and drying the steel wire meshes for subsequent usage; 5) fixing the steel wire meshes coated with the coating in a casting mold; and 6) fusing low and medium alloy to obtain molten steel and pouring the molten steel into the casting mold so as to obtain the composite material after solidification of the molten steel. The invention belongs to the technical field of preparation of mechanical materials.

Description

technical field [0001] The invention relates to a method for manufacturing a composite material, in particular to a method for manufacturing a zirconium corundum ceramic ball-low alloy steel composite material; it belongs to the technical field of mechanical material manufacturing. Background technique [0002] The machinery used for mining in mines consumes a lot of wear and tear, and the amount of metal wear-resistant materials consumed by abrasive wear alone reaches more than 3 million tons every year. The economic loss is more than 100 billion yuan. The main reason is that most of the working parts are made of metal, and the working objects faced in mines are non-metals with high hardness. The hardness of the former is much lower than that of the latter. It needs to be replaced in a few days, resulting in increased costs and downtime losses. Complex working objects and harsh working conditions require that the material of the processed parts should be corresponding to ...
