Description
Technical field
The present invention relates to a kind of method for preparing the wear-resisting composite liner of metal/ceramic.
Background technology
Need in the industries such as electric power, metallurgy, mine, coal, chemical industry to carry a large amount of sand, stone, coal dust, lime-ash etc. to produce material, and need produce material to these in the later stage and handle.What carry, the most often run in the storage process is the wear problem of transportation equipments such as pipeline, liner plate, so the performance such as wear-resisting, anti-corrosion of transportation equipment affects security, stability and the production efficiency of transportation and production to a certain extent.
Usually the liner plate that adopts in the industrial transport equipment has high manganese steel lining plate, cast iron lining plate, cast stone lining and cast stone etc., but owing to have different shortcomings separately, affects the life-span and the wearability of liner plate.Therefore, carry out the research of liner plate novel material, new texture, new prepn process, work-ing life, production efficiency and the market competitiveness etc. of further raising transportation equipment are all had important practical sense.Relative ordinary metallic material, stupalith have advantages of good abrasion, performance such as corrosion-resistant.But reason such as big and processing difficulties has hindered its direct use in handling equipment owing to stupalith fragility.If pottery and metallic substance are processed the sintering metal composite liner, then this metal/ceramic composite liner will have the advantage of two kinds of materials concurrently, have good comprehensive performances, can satisfy and produce actual needs.
At present; The approach that obtains the wear-resisting composite liner of metal/ceramic mainly contains two kinds: the one, utilize ceramic-metal produced with combination know-why; Through bonding, weld, inlay, riveted joint, socket and domes technology, various wear-resistant ceramic sheets, piece brick are compounded in wearing face inside and outside the workpiece, thereby form a surface with excellent wear-resisting property; And matrix still adopts metallic substance, prepares the metal/ceramic composite liner; The 2nd, coated ceramic can realize the compound of pottery and metal in the metallic surface, prepares composite liner.
Utilize the composite liner of ceramic-metal produced with combination know-why preparation to compare with traditional high-alloy casting; The workplace wear resistance is higher; Can make the whole wear-and corrosion-resistant of workpiece improve several times to more than several times work-ing life, but exist problems such as production cost height, the cycle is long, efficient is low.Chemical vapor deposition (CVD), physical vapor deposition (PVD), physical chemistry vapour deposition (PCVD) etc. are arranged the traditional method of ceramic coated but higher price, complicated manufacturing process and lower productivity etc. all become the bottleneck of its widespread use of restriction, therefore needs the novel process of development and preparation metal/ceramic composite liner.
The seventies in 20th century; The self propagating high temperature synthetic technology that has been born, (Self-propagating High-temperature Synthesis is a kind ofly to utilize chemical reaction self heat release to make reaction oneself continuity SHS) to the self propagating high temperature synthesis method; A kind of new technology of final synthetic material requested; It is simple that it has equipment, and technical process is short, the production efficiency advantages of higher.
Nowadays, the composite steel tube of self propagating high temperature synthetic technology preparation has obtained industrial application preferably, but is based on the self propagating high temperature synthetic technology, and the research that generates ceramic coating at surface of steel plate is actually rare.This major cause is that coating burning in plane is synthesized and on technology, implements comparatively difficulty that compare with forming coating in the steel pipe, reaction does not have restraint force; So it is very fierce; The system calorific loss is also bigger, be difficult to as dynamic method, apply external force field, so the densification of coating is also very difficult in addition.In addition, because the wettability of most of potteries and metal base is bad, bring sizable difficulty also for the preparation of coating.But along with developing rapidly of science and technology production and technology, researcher has been obtained related developments in this field: Ma Zhuan etc. are at " corrosion science and guard technology " 2010 the 22nd the 1st phases of volume " fine copper surface SHS reaction thermal spraying Al
2O
3The performance study of base composite ceramic coating " adopt self propagating high temperature building-up reactions flame plating technology in the literary composition, Al-CuO thermite reaction system is incorporated in the spray material, at fine copper surface preparation Al
2O
3The base composite ceramic coating.The result shows, the combining of SHS reaction thermal spraying layer and matrix is better than conventional thermospray, is aided with the bottoming of Ni-Al alloy, and compound coating 500 degree thermal shock circulation 40 times down are still excellent.Burnt Anyuan etc. utilize gravity separation SHS technology in " heat processing technique " 2010 the 39th volumes the 16th phase " gravity separation SHS legal system is equipped with the research of Ceramic Composite steel plate " literary composition surface of steel plate has directly prepared ceramic composite coating on roll coil of strip limit, has measured coating hardness.The result shows that the coatingsurface of Ceramic Composite steel plate is smooth, and its hardness is more than 1100HV.
Though research has in this respect obtained certain progress, correlative study both at home and abroad is also less, and relevant additive is unclear to the mechanism of wear-resistant coating performance impact, needs further research.
