Abstract
An electric conducting tip for the supersonic arc-spraying machine is composed of the cylindrical front half made of cermat prepared from tungsten carbide, titanium carbide, tatalum carbide, niobium carbide and chromium (or cobalt or nickel) of carbide for high antiwear performance, and the cylindrical back half made of Cu alloy prepared from Cu, Cr, Zr, Mg and Ce or Y alloy.
Description
Affiliated technical field
The present invention relates to a kind of supersonic electric arc flush coater ignition tip and manufacture method thereof.
Background technology
The metal spraying by electric arc machine is when work, and by the two one metal wires generation electric arc of ignition tip, because the high temperature action of electric arc, wire is melted, and the particle jetting of atomizing and formation high-speed motion forms coating to surface of the work under the impact of gases at high pressure.
Ignition tip will be given wire with current delivery as conductor when electric arc spraying, therefore excellent conducting performance will be arranged, to guarantee simultaneously and good contact the wiry, require ignition tip and surface contacted resistance wiry little, otherwise may cause heating, the ablation part.
Sliding friction between ignition tip and the wire has caused the quick wearing and tearing of ignition tip, according to practical experience, use the ignition tip of red copper or copper alloy, under continuous duty, general 1-2 hour, ignition tip will enlarge and causes the current interruption phenomenon because of groove and endoporus appear in wearing and tearing, and 3-4 hour will be because of wearing and tearing lose normal ability to work, the ignition tip that need more renew.
During metal spraying by electric arc electric arc there is very strict requirement, steadily to allowing the even tiny metallic particles of abundant fusion of wire and formation play crucial effect, the arc balance of going simultaneously can make the motlten metal particle flux of atomizing successfully arrive surface of the work and form the sprayed coating of densification the row arc.If ignition tip endoporus serious wear, locus wiry will change, and causes the dislocation of two one metal wires and the focusing of two one metal wire ends inaccurate; Contact between wire and the ignition tip simultaneously unstable, the contact resistance increase; These all will cause row arc shakiness, serious will current interruption, thereby influence coating quality and production efficiency greatly.
Summary of the invention
For the serviceability and the service life of improving ignition tip, the object of the present invention is to provide a kind of supersonic electric arc flush coater ignition tip and manufacture method thereof that on material, structure and processing technology, has breakthrough.
The technical solution used in the present invention is as follows:
One, supersonic electric arc flush coater ignition tip: be made up of cylinder ignition tip front end, cylinder ignition tip rear portion integral body, have screw thread on the small cylinder at cylinder ignition tip rear portion, whole ignition tip center has small through hole.The ceramic-metallic cylinder ignition tip front end of high abrasion and high conductivity and be sintered into one than the cylinder ignition tip rear portion of the copper alloy of high-wearing feature.
Two, the manufacture method of supersonic electric arc flush coater ignition tip:
1) ceramic-metallic composition
Weight percentages
Tungsten carbide 65～74
Titanium carbide 4～10
Ramet 2～5
Niobium carbide 1～3
Chromium carbide 4～9
Cobalt 10～15

The particle diameter of above-mentioned each component is 80～250 orders;
2) composition of copper alloy
Weight percentages
Copper surplus
Chromium 0.5～1.2
Zirconium 0.1～0.5
Magnesium 0.08～0.1
30～45% ceriums or yttrium rare earth alloy 0.1～0.3
3) manufacture method
80～250 purpose cermet each component powder are stirred, by the partly size of the requirement mould compression moulding of ignition tip cermet, carry out sintering, 1300～1480 ℃ of sintering temperatures, sintering time 1～2 hour then in vacuum drying oven or in the gas shield stove; The cermet that sintering is finished is put into another mould; above-mentioned copper alloy each component is carried out melting with nitrogen protection and stir in intermediate frequency furnace; pour into then and laid in the ceramic-metallic mould; mould waters temperature and is controlled between 1200～1300 ℃; sintering is together securely for the depanning of cooling back, cermet part and copper alloy part.
The present invention compares with background technology, and the useful effect that has is:
Existing arc-spraying machine ignition tip all is whole to be made with red copper, the performance characteristics of red copper be electric conductivity better but wearability is very poor.The wearing and tearing of ignition tip mainly occur in front end, the present invention structurally uses the ignition tip front end material of high abrasion, and in that the ignition tip rear portion is close with red copper with electric conductivity but the copper alloy that wearability improves greatly, significantly improve electric conductivity, the wearability of ignition tip, the present invention is rational in infrastructure, be easy to processing.
Description of drawings
Accompanying drawing is a structural representation of the present invention.
The specific embodiment
As shown in drawings, the present invention is made up of cylinder ignition tip front end 1, cylinder ignition tip rear portion 2 integral body, has screw thread on the small cylinder 4 at cylinder ignition tip rear portion 2, and whole ignition tip center has small through hole 3; The ceramic-metallic cylinder ignition tip front end 1 of high abrasion and high conductivity and than the cylinder ignition tip rear portion 2 of the copper alloy of high-wearing feature both are sintered into one.
