Description
Technical field:
The present invention relates to the Ni base noncrystal alloy, a kind of technological method for preparing amorphous alloy coating is provided especially, and the thinking that makes the excellent properties of non-crystaline amorphous metal be able in industry, use.
Background technology:
Since non-crystaline amorphous metal is found, because its particular structure and performance have caused people's very big concern.Especially since the nineties in 20th century,, all the more so owing to large block amorphous appearance with high glass forming ability.But work hardening, takes place, and starting of single shear zone can be taken place as crystal boundary and dislocation owing to there is not lattice defect in non-crystaline amorphous metal unlike conventional alloys when distortion, brittle rupture just takes place when not reaching yield strength, causes catastrophic inefficacy.Like this, amorphous is restricted as the application of structured material, and therefore, amorphous should be the research direction of tool prospect as the application of coating.In addition, non-crystaline amorphous metal has good wear and corrosion behavior, and this has also supported the possibility of non-crystaline amorphous metal as surface applications.In early days, people prepare amorphous alloy coating with the method for laser treatment and sputter, mainly concentrate on binary alloy and minority multicomponent alloy, but, the large-block amorphous alloy component that these technology do not utilize recent development to get up, and himself limitation is arranged, be of limited application.
Summary of the invention:
The object of the present invention is to provide a kind of technology for preparing supercoat, the range of application that this technology is possible is more extensive, can provide a kind of good potential method and thinking for the preparation amorphous alloy coating.
The invention provides a kind of preparation method of ni-based amorphous alloy coating, with the amorphous powdered alloy is raw material, adopt the supersonic speed heat spraying method to prepare amorphous alloy coating, it is characterized in that: described amorphous powdered alloy is made up of following element and unavoidable impurities, mass percent:
Zr 27～29；
Ti 10～13；
Si 0.5～1；
Sn 4～6；
The Ni surplus.
Ni-based amorphous alloy coating of the present invention, that has utilized that recent development gets up has high glass forming ability (～3mm) a Ni base large amorphous alloy composition.That has adopted that recent development gets up replaces the supersonic speed of oxygen with air (the spray powders granularity is :+16-45 μ m for High Velocity Air Fuel, HVAF) hot-spraying techniques.Because crystallization and oxidation in spraying process, its amorphous content is about: 40%～60%.
Hot-spraying techniques is industrial a kind of technology for preparing supercoat commonly used, applied range, and can make full use of the large-block amorphous alloy component that recent development is got up, therefore, it is a kind of good potential technology of preparation amorphous alloy coating.We utilize the gas atomization technology to prepare amorphous powdered alloy, method with the supersonic speed thermospray prepares amorphous alloy coating then, and make full use of the large block amorphous composition that recent development is got up, developing industry amorphous alloy coating with high glass forming ability.Why selecting the supersonic speed hot-spraying techniques, is the coating densification because of its preparation, and voidage is low, helps the application of coating in the aqueous corrosion medium.
