Abstract
The invention provides a preparation method of a nanoceramic material for the surface of a thermal spraying mold. The preparation method comprises the following steps of uniformly mixing nano-scale Cr2O3, Al2O3-MgO and Al2O3-SiO2, adding an auxiliary liquid into the mixture to obtain material slurry, carrying out granulation by a pelletizer, carrying out sintering treatment on the granular material, screening the sintered granular material to obtain the spraying particles with particle sizes of 20-35 micrometers, and directly spraying the particles to a pretreated base sample by a thermal spraying device. The nano-scale Cr2O3, Al2O3-MgO and Al2O3-SiO2 as raw materials and NiCrAlY are combined and are processed to form the spraying material so that repaired mold quality is improved and mold thermal spraying repair efficiency is improved. The preparation method is suitable for mold repair in small and medium-sized enterprises, reduces a mold manufacturing cost and reduces a production cost.
Description
Technical field
The present invention relates to field of thermal spray, particularly relate to a kind of preparation method of thermospray die surface nano ceramic material.
Background technology
Thermospray refers to a series of process, in these processes, trickle and dispersion metal or nonmetallic coated material, with one fusing or semi-molten state, deposit to a kind of matrix surface through preparation, forming certain spray deposited layer. it utilizes certain thermal source (as electric arc, plasma spraying or combustion flame etc.) Powdered or thread metal or non-metallic material are heated to melting or semi-melting state, then itself or pressurized air is stayed to be ejected into pretreated matrix surface with certain speed by flame, deposit and form a kind of technology with the top coat of various function.At present when carrying out maintenance process to mould, need die surface thermospray one deck repair layer, the position be worn on repairing mould, current die surface hot-spraying techniques, efficiency is not high and die life after repairing is relatively short, rehabilitation cost is comparatively large, is not suitable for medium and small sized enterprises and uses.Therefore, mold hot spraying remediation efficiency is not solved high and repair rear mold life-span shorter problem and just seem particularly important.
