Abstract
The utility model discloses a polar plate of a logging instrument, which comprises a substrate, wherein a protective coating layer is formed on the substrate. By forming the protective coating layer which is made of tungsten carbide preferably on the substrate of the polar plate, the abrasion resistance of the polar plate is increased over 20 times compared with that of the polar plate without a tungsten carbide coating layer.
Description
Technical field
The utility model relates to a kind of pole plate that is used for logging instrument.
Background technology
The pole plate that has the gage beam that is used for logging instrument now is when going into the well use, and pole plate constantly rubs with the borehole wall in well, is easy to cause the wearing and tearing of pole plate, has influence on the measurement effect of pole plate, and maintenance cost is very high.
The utility model content
The technical problems to be solved in the utility model provides a kind of pole plate of logging instrument, and this pole plate can strengthen anti-wear performance greatly.
In order to address the above problem, the utility model provides a kind of pole plate of logging instrument, and this pole plate comprises matrix, is formed with one deck protective coating on this matrix.
Preferably, described protective coating is for being coated in the tungsten-carbide powder on the described matrix by high velocity of sound.
Preferably, the thickness of described protective coating is 0.1～0.3mm.
The utility model is by forming one deck protective coating on the matrix of pole plate, preferably adopting tungsten carbide is the protective coating of material, and the abrasion resistance of pole plate is compared with the pole plate abrasion resistance that does not have tungsten carbide coating, has improved more than 20 times.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
As shown in Figure 1, the utility model comprises: matrix 1 is formed with one deck protective coating 2 on this matrix 1.In the present embodiment, protective coating 2 is for being coated in the tungsten-carbide powder on the matrix 1 by high velocity of sound.The thickness of protective coating 2 can be 0.1～0.3mm.
The utility model is owing to by form the protective coating 2 of one deck tungsten carbide on the matrix 1 of pole plate, improved the abrasion resistance of pole plate greatly, and the abrasion resistance of pole plate is compared with the pole plate abrasion resistance that does not have tungsten carbide coating, has improved more than 20 times.
In sum; it below only is preferred embodiment of the present utility model; be not to be used to limit protection domain of the present utility model; therefore; all any modifications of within spirit of the present utility model and principle, being done, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
Claims (3)
