Technical field
The present invention relates to thermal power plant boiler pipeline corrosion protection technical field of alloy material, and in particular to one kind is for improving thermoelectricity
The nickel tantalum alloy material of factory's boiler tubing interface bond strength.
Background technique
Waste incineration is a kind of main means of current garbage disposal, but component of refuse is extremely complex, content of organics
Height, simultaneously containing harmful substances such as a large amount of Cl, S and alkali metal, it is heated that these ingredients will lead to Boiler Metallic after high temperature incineration
Face seriously corroded.The factors such as high temperature and pressure and corrosive wear and abnormal running cause boiler tubing early stage booster to have become shadow
Ring the principal element of power industry safe operation.Increase to accident rate, limits the popularization and development of garbage incineration technology.
Therefore, solve the problems, such as that garbage burning boiler high temperature corrosion is most important.
The effective means that prevention is a kind of prolonged boiler normal operation period is carried out to boiler tube using plasma spray technology.?
The country, the sprayed protection technology mainly used at present have: aluminium-plated protection is 660.4 DEG C since the fusing point of aluminium is low, in low temperature ring
Effect is pretty good under border, but its creep strength is low, wears no resistance, and the components such as high-temperature high-pressure boiler " four pipes " often need simultaneously
Bear certain abrasive action, these factors make it is aluminium-plated after protective effect it is undesirable；Surfacing Ni-W alloy coat, although surfacing
Layer is well combined, and is worn and is corroded slightly, but its technique shortcoming is that remelting temperature is excessively high, causes pipe deformation, large area
Using having any problem；The country also has to be protected using aluminising, chromising, but hot-dip process is generally only applicable to single-element composition
Coating, and higher operating temperature required by this method can generate centainly the tissue result and performance of basis material
