Abstract

A high and low voltage contactor of ZrB<2> -Ag nano-composite coating comprises a moving contact base material 1, a fixed contact base material 3 and a ZrB<2> -Ag nano-composite coating 2 on the base material 1 and 3. The ZrB<2> -Ag nano-composite coating 2 is comprised of a diffusion layer 4, a bottom layer 5 and a ZrB<2> -Ag nano-composite coating layer 6. By the high-energy small-size surface effects and the quantum effects of the ZrB<2> nano-surface with particle diameter of 60 nanometer, the high and low voltage contactor contact not only maintain electrical conductivity and thermal conductivity of the original silver coating, but also improves the surface hardness, wear resistance and electric erosion resistance of the contactor, so as to promote the service life of the high and low voltage contactor about 1.2 times and reduces the cost about 0.5 times.

Description

ZrB 2The high-low pressure probe of contactor of-Ag nano-composite plate
The utility model relates to the moving contact and the fixed contact of high-low pressure contactor, that adopt on the surface of this contact is ZrB 2-Ag nano-composite plate.
The technical field probe of contactor is widely used on the various contactors of high and low voltage electrical equipment, by it realize electric current conducting and closed, be the critical component of the various contactors of high-low pressure.It requires overlay coating to have good electrical conductivity, thermal conductivity and corrosion resistance, and silver (Ag) coating can reach above-mentioned requirements at present; But the case hardness of silvering and molten point are lower, resistance to wear and electric erosion resistance poor ability, thus useful life is not high.
The background technology the purpose of this utility model is lower at present contacts of contactor case hardness and molten point, and resistance to wear and anti-galvanic corrosion ability are relatively poor, and the problem that useful life is not high proposes that a kind of hardness height, resistance to wear are good, the ZrB of long service life 2-Ag nano-composite plate, it not only can keep the satisfactory electrical conductivity and the heat conductivility of silvering, but also has increased hardness, resistance to wear, the anti-galvanic corrosion ability on probe of contactor surface, thereby has improved 1.2 times of useful lifes of probe of contactor.It is by nanoscale ZrB 2Surperficial high energy small size skin effect and quantum effect realize that case hardness is brought up to Hv457 by Hv210, improve 2.1 times; Again because of nanoscale ZrB 2Not only hardness height (up to Hv2300), and molten point also high (reaching 3100 ℃), thereby the resistance to wear and the electric erosion resistance of raising composite deposite.Realized making the probe of contactor life-span to improve 1.2 times.
Summary of the invention ZrB described in the utility model 2The high-low pressure probe of contactor of-Ag nano-composite plate comprises the base material be made up of red copper and the ZrB on the substrate surface 2-Ag nano-composite plate, this composite deposite is formed by three layers: one deck is and the diffusion layer of base material strong bonded, and one deck is the bottom that combines with diffusion layer, and outermost one deck is thicker ZrB 2-Ag nano-composite plate.
Description of drawings and embodiment Fig. 1 are ZrB 2The high-low pressure probe of contactor of the multiple crawl coating of-Ag nanometer.
Fig. 2 is the local amplification of A among Fig. 1.
The utility model is described in further detail below in conjunction with accompanying drawing: as shown in Figure 1, and ZrB described in the utility model 2The high-low pressure probe of contactor of-Ag nano-composite plate comprises moving contact base material (1), fixed contact base material (3) and ZrB 2-Ag nano-composite plate (2).ZrB as shown in Figure 2 2-Ag nano-composite plate, form by three layers: (4) are diffusion layer, and (5) are bottom, and (6) are ZrB 2-Ag nano-composite plate.
Characteristics of the present utility model are: can make probe of contactor reach the characteristics that case hardness height, resistance to wear are good, electric erosion resistance can be high, improve 1.2 times useful life, cost reduces by half times economic and technical norms.
