Embodiment Construction

[0032] Embodiment of the present invention production process step process:

[0033] (1) Ingredients

[0034] Raw material composition weight ratio: 95% of nickel, 4.55% of aluminum, 0.15% of manganese, 0.15% of titanium sponge, and 0.15% of rare earth are equipped with raw materials;

[0035] The invention changes the relatively simple formula of the existing nickel-aluminum alloy wire, and adds trace elements, especially rare earth elements, into the formula, which plays a very important role in improving the performance of the product. At the same time, in the above-mentioned ingredients, the ratio of various ingredients is also very important. Adding aluminum and titanium elements to the nickel-based alloy can improve the bonding strength between the coating and the substrate. Aluminum element has a strong self-passivation effect, so it can improve the surface quality and corrosion resistance of the coating. Titanium has the characteristics of high strength, good corros...

Abstract

The preparation method for Ni-Al alloy wire comprises: (1) preparing material by intergradient ratio as: 3-7% Al, 0.12-0.18% Mn, 0.12-0.18% titanium sponge, 0.12-0.18% rare-earth, and Ni; (2) vacuum melting; (3) forging; (4) thermal rolling; (5) coarse drawing; (6) thermal treating; (7) boiling; (8) precise drawing; (9) finishing. This product has super inner performance, clear external appearance, and well resistance to chemical and high-temperature corrosion; brings little pollution, and special fit to the part under bas condition or required high-grade and performance.

Description

technical field [0001] The invention relates to the technical field of alloys, in particular to a thermal sprayed nickel-aluminum alloy wire and its preparation. Background technique [0002] Since the advent of thermal spray (Thermal Spray) technology, after continuous development, thermal spray equipment, materials, and processes have made great technological progress. In terms of arc spraying (Arc Spray), it is especially suitable for large-area spraying primer due to its high spraying bonding strength, low energy consumption, low cost, high efficiency, easy process control, and stable spraying quality. In the case of metal arc spraying, in order to improve the bonding strength between the coating and the substrate, it is necessary to spray the corresponding bottom primer first. Although aluminum bronze wire can make up for some defects of other arc spraying primer materials, it will generate a lot of smoke layer during spraying, causing serious pollution and causing hea...
