Abstract
The present invention relates to a kind of means of defences in thermal spraying hole, change original thermal spraying protective materials, use the very low organic silicon rubber of cost or organosilicon cave, organic silicon rubber or silicone are the organic polymers that can be extremely cracked into ceramics individually, heatproof, resistance to oxidation characteristic are notable, retention properties can stablize within the scope of 200~300 DEG C.The present invention is easy to operation, and sealing of hole effect is good, has good thermal spraying protection effect, and cheap, and cleaning is convenient.
Description
Technical field
The present invention relates to a kind of means of defence, especially a kind of means of defence of thermal spraying plug-hole, at low cost with protection,
The characteristics of ensureing coating quality.
Background technology
For some parts with holes in thermal spray process, the position for being related to hole needs device to hole to be protected.Existing protecting hand
Section mostly uses high temperature-proof adhesive tape or clay, such as imported from America De Veulle 3M adhesive tapes or clay, these material prices costly, together
When, clay protection cleaning is difficult, and then to there may be protection not tight for the protection method of adhesive tape, influences coating quality.
Invention content
The object of the present invention is to provide a kind of means of defences in thermal spraying hole, part are realized in thermal spray process, to not
It needs the hole sprayed to carry out effective protection, while ensureing coating quality, has the characteristics that easy to clean, at low cost.
The technical scheme is that the means of defence in the thermal spraying hole includes the following steps：
1) prepare part, the piece surface needs to carry out thermal spraying process, and presence need not spray, need to carry out
The hole of protection；
2) prepare organic silicon rubber, and process organic sillicon rubber blocking, the hole cooperation of the rubber stopper and protection, and rubber
Plug end is machined with groove, and rubber stopper is filled in hole；
3) cutting removal protrudes the extra organic silicon rubber plug at position outside the hole of protection, the organic silicon rubber left after cutting
Plug should be higher than that 1~3mm of coating to be painted；
4) according to technological requirement, thermal spraying is carried out to part, after thermal spraying, spray-on coating is ground, exposes organic silicon rubber
Plug, organic silicon rubber plug is removed out of hole, and spraying is completed.
In the means of defence, the material in the hole of closure is organosilicon cave, and the organosilicon cave is injected into protection
Cutting and part thermal spraying are carried out in hole, after solidification.
The present invention changes original thermal spraying protective materials, uses cost very low organic silicon rubber or organosilicon
Cave, organic silicon rubber or silicone are the organic polymers that can be extremely cracked into ceramics individually, and heatproof, resistance to oxidation characteristic are notable, energy
Enough retention properties within the scope of 200~300 DEG C are stablized.In thermal spray process, the temperature that flame stream touches part must control
Within 200 DEG C, the mechanical property of part to be sprayed is otherwise influenced whether, therefore, organic silicon rubber or silicone are (logical as plug-hole
Hole) choke material have good thermal stability property.In addition, organic Si-R keys and Si-O existing for organic silicon rubber plug or silicone
Key, Si-O keys are sufficiently stable, and organosilicon after the ceramic of silicon rubber surface layer, can significantly stop by portion's ceramic after being heated
Transmission of the heat to its inner silicone；And Si-R keys make it have preferable flexible profile-followed elastic deformability, it can after filling
Tight closure hole, fragments into organic molecule after Si-R keys are heated and part is volatilized, and organic silicon rubber or organosilicon cave is made to exist
Embrittlement variation occurs after heated, it is easy to clean.The present invention is easy to operation, and sealing of hole effect is good, has good thermal spraying anti-
Effect is protected, and cheap, cleaning is convenient.
Specific implementation mode
A kind of means of defence in thermal spraying hole includes the following steps：
1) prepare part, the piece surface needs to carry out thermal spraying process, and presence need not spray, need to carry out
The hole of protection；
2) prepare organic silicon rubber, and process organic sillicon rubber blocking, the hole cooperation of the rubber stopper and protection, and rubber
Plug end is machined with groove, and rubber stopper is filled in hole；
3) cutting removal protrudes the extra organic silicon rubber plug at position outside the hole of protection, the organic silicon rubber left after cutting
Plug should be higher than that 1~3mm of coating to be painted；
4) according to technological requirement, thermal spraying is carried out to part, after thermal spraying, spray-on coating is ground, exposes organic silicon rubber
Plug, organic silicon rubber plug is removed out of hole, and spraying is completed.
The means of defence in the thermal spraying hole can also be realized by following steps：
1) prepare part, the piece surface needs to carry out thermal spraying process, and presence need not spray, need to carry out
The hole of protection；
2) prepare organosilicon cave, organic silicone is injected in the required hole protected, waits for its solidification, the organosilicon cave after solidification
It is higher by surface to be sprayed；
3) cutting removal protrudes the extra organosilicon cave at position outside the hole of protection, and the organosilicon cave left after cutting, which is higher than, to be waited for
1~3mm of sprayed coating；
4) according to technological requirement, thermal spraying is carried out to part, after thermal spraying, spray-on coating is ground, exposes organosilicon cave, it will
Organosilicon cave is removed out of hole, and spraying is completed.
Embodiment 1
Certain part carries out thermal spraying, needs the hole that need not be sprayed on part to be blocked in thermal spray process, described
Hole size be φ 7mm, need thickness be 0.40~0.55mm nickel chromium triangle-chromium carbide coating, concrete operation step is such as
Under：
1) prepare part, the piece surface needs to carry out thermal spraying process, and presence need not spray, need to carry out
The hole of protection；
2) prepare organic silicon rubber, and process organic sillicon rubber blocking, the hole cooperation of the rubber stopper and protection, and rubber
Plug end is machined with groove, and rubber stopper is filled in hole；
3) cutting removal protrudes the extra organic silicon rubber plug at position outside the hole of protection, the organic silicon rubber left after cutting
Plug is higher than coating 1.5mm to be painted；
4) according to technological requirement, thermal spraying is carried out to part, after thermal spraying, spray-on coating is ground, exposes organic silicon rubber
Plug, organic silicon rubber plug is removed out of hole, and spraying is completed.
By the above method, the protection effect in thermal spraying hole is good.
