Abstract
The invention relates to a high-temperature wear-resistance and anti-corrosion thermal spraying alloy wire characterized by comprising the following components by weight percent: Ni of not less than 38%, Cr of not less than 24%, W of more than 2.7%, Mo of more than 3.6%, rare earth of not more than 0.2% and the balance of copper. The invention has the advantages of homogenizing and refining metallic phase and improving wettability, percentage of elongation and welding performance. The product has good welding performance for wires and transformers, is be easier to generate favorable affinity with base materials (solid materials) and has bright and full welding points.
Description
Technical field
The present invention relates to a kind of product and can replace nickeliferous high-temperature wear-resistance and anti-corrosion thermal spraying alloy wire, be used to make slide fastener, wrist-watch watch chain and watchcase and decoration technology etc., belong to new material technology field.
Background technology
As everyone knows, copper-nickel alloy is to be the copper alloy of main alloy element with nickel, copper-nickel alloy particularly German silver (GU-Ni-Zn) not only has argenteous outward appearance, and have good solidity to corrosion, higher intensity and favorable manufacturability energy, be widely used for making the object that slide fastener, wrist-watch watch chain and watchcase and decoration technology etc. contact with human body.
Discover that human body contacts with nickel-containing material for a long time, and sensitization and carcinogenic influence are arranged.Western countries are more and more stricter to the use of nickeliferous goods, the trend with nickel-containing alloys manufacturing and human body contact product also occurred forbidding.
In order to seek the surrogate of nickeliferous German silver material, Shanghai Communications University has carried out the laboratory study and the mechanism discussion of the aspects such as composition, color and corrosion of the system of going deep into and the progress of making a breakthrough property to copper MnZn aluminium alloy.
The ubiquitous shortcoming of present existing white copper alloy without nickel be (1) the constituent content scope of giving too wide, the tone of resulting alloy, performance difference are too big.Chromaticity scope as white is: 0≤a*＜5,7≤b*＜15, in fact work as a*=4.9, and during b*=14.9, colorimetric purity is up to 16, and the tone of alloy has been reddish yellow, rather than silvery white, differs greatly with the color of German silver.
Summary of the invention:
The present invention aims to provide a kind of high-temperature wear-resistance and anti-corrosion thermal spraying alloy wire, to prepare the white Cu-Mn alloy of melting by horizontal continuous-casting technology and cold drawn cold-rolling process and make wire rod, product not only surface is white in color, corrosion-resistant, color stability is good, and with low cost, good processability, do not harm HUMAN HEALTH, can make slide fastener, wrist-watch watch chain and watchcase and decoration technology etc. by instead of zinc copper-nickel alloy wire rod.
Main points of the present invention are the component and the method for manufacturing wire thereof of alloy, comprise following content: the component of high-temperature wear-resistance and anti-corrosion thermal spraying alloy wire (weight percent) is: Ni 〉=38%, Cr 〉=24%, W＞2.7%, Mo＞3.6% is not more than 0.2% rare earth, and surplus is a copper.
The present invention makes wire rod by horizontal continuous-casting technology and cold drawn, cold-rolling process with above-mentioned alloy.Behind the alloy non-vacuum melting, thermal insulation deslagging is made wire rod with above-mentioned alloy.Behind the alloy non-vacuum melting, thermal insulation deslagging, burn the casting temperature and remain on 1050-1150 ℃, continuous casting becomes the line base on horizontal caster, again with the cold drawn one-tenth work in-process of line base base, behind 700-750 ℃ of high temperature annealing 120-240 minute, pickling, cold rolling one-tenth lenticular wire base, behind 670-720 ℃ of high temperature annealing 120-240 minute, pickling, final cold drawn one-tenth finished product wire rod.
The present invention has following advantage and effect: metallographic is more even, and more refinement has improved wettability, elongation, welding property; This product has good welding property to wire rod, transformer, and easier and base material (Gu material) produces good affinity, and solder joint is bright, and is full.
Embodiment
High-temperature wear-resistance and anti-corrosion thermal spraying alloy wire comprises that following component (weight percent) is: Ni 〉=38%, and Cr 〉=24%, W＞2.7%, Mo＞3.6% is not more than 0.2% rare earth, and surplus is a copper.
Production technique of the present invention is: by horizontal continuous-casting technology and cold drawn, cold-rolling process, above-mentioned alloy is made wire rod.Behind the alloy non-vacuum melting, thermal insulation deslagging is made wire rod with above-mentioned alloy.
Behind the alloy non-vacuum melting, thermal insulation deslagging, burn the casting temperature and remain on 1050-1150 ℃, continuous casting becomes the line base on horizontal caster, again with the cold drawn one-tenth work in-process of line base base, behind 700-750 ℃ of high temperature annealing 120-240 minute, pickling, cold rolling one-tenth lenticular wire base, behind 670-720 ℃ of high temperature annealing 120-240 minute, pickling, final cold drawn one-tenth finished product wire rod.
