Abstract
The utility model provides a ceramic gasket with a conductive coating. The ceramic gasket with the conductive coating comprises the ceramic gasket and the conductive coating, wherein the conductive coating is uniformly coated on the surface of the ceramic gasket by adopting a thermal spraying technology. The ceramic gasket with the conductive coating, provided by the utility model, has the advantages that various defects and problems of difficult arc strike, easiness in arc breaking, bad arc stiffness and the like caused by the bad conductivity of the traditional ceramic gasket in the single welding process for both surfaces are solved, the structure is simple, the cost is low, the conductive coating is suitable for ceramic gaskets in various shapes, thus the welding process is more stable, and a welding connector with higher quality can be obtained.
Description
Technical field
The utility model belongs to welding technology field, particularly a kind of ceramic substrate that has conductive coating.
Background technology
One side welding with back formation technology is a kind of quality that can effectively guarantee welding point, improves welding efficiency, and the welding procedure that reduces production costs.Widely used pressure is shaped in this technology, is meant to be added with at the back side of weld seam to set off material.Pottery be often adopt set off one of material, can the support metal bath when welding and prevent to leak the material of molten bath under the pressure appearance of weld.Ceramic substrate has appropriate melting point, grooving surface portion fusing under the effect of arc heat, and the butt welded seam metal plays lubrication, increases the flowability of liquid metal, makes the welding bead back-welding shape good, and is level and smooth, and its hygroscopicity is little, positioning stablity.
But in the welding operation process of reality, find ceramic substrate because the non-conductive property of itself, the problem below the appearance easily: one of which during welding, is difficult for the electric arc that ignites on the surface of pottery; Its two, in the process of welding, the deflection of electric arc is poor, is difficult for the through welding molten bath; Its three, the process of welding is unstable, is prone to current interruption.
The utility model content
To the problem that background technology exists, the utility model provides a kind of ceramic substrate that has conductive coating.
For solving the problems of the technologies described above, the utility model adopts following technical scheme.
A kind of ceramic substrate that has conductive coating is characterized in that: comprise ceramic substrate and conductive coating; Conductive coating is to adopt the method for thermal spraying evenly to be coated in the ceramic substrate surface.
Said conductive coating is processed by low-carbon steel material, and its thickness is 0.1-0.3mm.
Compared with prior art, the utlity model has following advantage and beneficial effect:
1, the surfaces coated of the utility model is covered with conductive coating, makes it have electric conductivity, but good conductive during welding, and arc stiffness is high, makes welding process more stable.
2, the utility model is simple in structure, low production cost, and conductive coating is applicable to the ceramic substrate of different shape, practical.
Description of drawings
Accompanying drawing is the structure diagram of the utility model.
Wherein, 1-ceramic substrate, 2-conductive coating.
The specific embodiment
Below in conjunction with embodiment shown in the drawings the utility model is described further.
The utility model comprises ceramic substrate 1 and conductive coating 2; Conductive coating 2 evenly is coated in ceramic substrate 1 surface; Conductive coating 2 is processed by low-carbon steel material, and its thickness is 0.1-0.3mm.
Adopt heat spraying method when making the utility model, with the thermal source of arc heat as thermal spraying, will process the low-carbon steel material of coating, transient heating is to plastic state or molten state, and high-velocity spray forms conductive coating 2 to the contact-making surface of ceramic substrate 1; When welding, conductive coating 2 can make arc stability, good, the easy starting the arc of deflection, be difficult for current interruption, forms good welding point.
Claims (2)
1. a ceramic substrate that has conductive coating is characterized in that: comprise ceramic substrate and conductive coating; Conductive coating evenly is coated in the ceramic substrate surface.
2. a kind of ceramic substrate that has conductive coating according to claim 1, it is characterized in that: said conductive coating is processed by low-carbon steel material, and its thickness is 0.1-0.3mm.
