Abstract
The invention belongs to the oxide ceramic and hot spraying crossing field, which is mainly applied to the manufacture of chrome oxide base ceramic powder used for oxygen-acetylene flame spraying. The chemical composition of the chrome oxide base ceramic powder used for the oxygen-acetylene flame spraying can be expressed as (expressed by mass percentage): (Cr2O3)t*(Al2O3)u*(SiO2)v*(TiO2)w*(Li2O)x*(K2O)y*Az, wherein, A is the sum total of MgO, CaO, Na2O, Fe2O3, etc.; T is less than or equal to 92 and more than or equal to 80, u is less than or equal to 8 and more than or equal to 1, v is lessthan or equal to 10 and more than or equal to 2, w is less than or equal to 4 and more than or equal to 0.5, x is less than or equal to 1 and more than or equal to 0.1, y is less than or equal to 1 and more than or equal to 0.1, and z is less than or equal to 0.5, and t plus u plus v plus w plus x plus y plus z is equal to 100. Because the ceramic material has lower melting point, a common oxygen-acetylene flame spraying method can be adopted to obtain a chromium oxide base ceramic powder coating layer with good cementing performance, high hardness and good thermal stability. Because the requirement of hot spraying power material to the equipment is low, the energy consumption is low, and the environmental requirement is low, the chrome oxide base ceramic powder can be widely applied in steel surface hot spraying ceramic in various occasions.
Description
Technical field:
The invention belongs to oxide ceramics and thermospray crossing domain, it is mainly used in oxygen-acetylene flame sprayed coating and uses the chromic oxide-based ceramic powder end.
Background technology:
The chromic oxide-based thermospray ceramic powder of existing market supply mostly is pure zirconia chromium powder end, and its chromic oxide composition (quality percentage) is 99%, and oxide compounds such as small amounts aluminium, titanium oxide, silicon oxide, magnesium oxide are only contained at other chromic oxide-based ceramic powder ends.Wherein, Cr
2O
3Content greater than, equal 92%.These hot spray powders are because Cr
2O
3Content is higher, and other oxide compound that wherein contains also is refractory oxide, and these compositions can not generate the low melting point phase, therefore generally is used for plasma thermal sprayed.
Do not see oxygen-acetylene flame sprayed coating Cr in the market
2O
3Based ceramic powder end production marketing is not seen relevant patent report yet.Because oxygen-acetylene flame sprayed coating is simple in structure, cheap than thermal spraying apparatus such as plasma thermal sprayed, detonation flame sprayings with equipment, and energy consumption is low, simple and convenient operation and maintenance, be convenient to advantage such as field condition operation.Therefore invent a kind of oxygen-acetylene flame sprayed coating and will have extensive market prospects and social effect such as energy-saving and cost-reducing with ceramic powder.
The purpose of this invention is to provide and a kind ofly can be used for that oxygen-acetylene flame sprayed coating uses, corrosion-resistant, resistance to wear, the chromic oxide-based ceramic powder end of high rigidity, good thermal shock.
Summary of the invention:
The present invention can be used for the chromic oxide-based ceramic powder of oxygen-acetylene flame sprayed coating, and its concrete chemical ingredients can be expressed as (representing with the quality percentage):

Ceramics powder composition of the present invention mainly is to design from the role of contained each element oxide pottery.The mullite that generates as titanium oxide, Lithium Oxide 98min and aluminum oxide and silicon oxide all can improve the thermostability of ceramic coating mutually, and silicon oxide, Lithium Oxide 98min, potassium oxide can reduce ceramic fusing point is convenient to oxygen-acetylene flame sprayed coating.
Embodiment:
Adopted oxygen-acetylene flame sprayed coating of the present invention with the chromic oxide-based ceramic powder end two kinds of ceramics powders that become assignment system, its composition sees Table 1.
The table 1 oxygen-acetylene flame sprayed coating chemical ingredients (quality %) at chromic oxide-based ceramic powder end:
To use ball mill mix grinding 24 hours by raw material that mentioned component is joined, be dehydrated into the mud shape.The gained pug is put into the vacuum deairing machine degassing, be squeezed into bulk, dry back sintering.The sintered material of gained is pulverized, sieved into the product of required various size ranges.
The 2000 type oxygen-acetylene flame sprayed coating rifles that the said products is produced with auspicious method spray the tinsel of surperficial sandblasting, and it is good to have obtained cementability, the ceramic coating that hardness is high.
