The front and rear casings of the aero-engine compressor are made of iron-based and nickel-based alloys respectively. During the process of use, the butt joints of the front and rear casings are in a vibrating state, and are prone to impact wear and damage after a period of wear. The life of the front and rear casings is shortened, so it is necessary to prepare a coating with high wear resistance to solve the wear of aviation equipment and prolong the service life of aviation equipment.

The piston and connecting rod mechanism are connected to the crankshaft. The crankshaft bears the pressure generated by the combustion of fuel mixture through the piston and connecting rod, and converts the reciprocating motion of the piston into rotating motion. A sliding component between the crankshaft and the connecting rod becomes a bearing, which together with the oil forms a sliding bearing.

The coating material of turbine outer ring of engine, especially aeroengine, requires advanced high temperature resistance, oxidation resistance, thermal erosion resistance and good sealing performance. Tungsten chromium cobalt alloy powder is a kind of coating material which can be used as the bottom layer. It has good adhesion and bonding strength with titanium alloy and other superalloys. The structure of the coating is evenly distributed. There are no cracks, delamination and separation between the coating and the substrate. It is a good bottom layer material for spraying.

When it comes to crankshaft, finely balancing the rotating assembly made by tungsten alloy counterweight is a step that is often overlooked.

Tungsten alloy counterweight is one of the heaviest material available in self-winding watches usage by the general public. Most watches sold today feature an automatic movement. These watches require nothing more than regular wear to keep them running. But how does an automatic watch self-wind? Do you need a watch winder if you only wear your watch from time to time?   

A stone crusher comprising a tungsten alloy counterweight rod provides an opportunity to change the weight and counterweight to optimize mass action in stone crusher.

Tungsten alloy counterweight has been used for weighting golf club head in order to gain better performance. The present club provides a golf club head with performance weighting through the use of a sole component composed of a tungsten alloy material.

Tungstate nanomaterial has a good application prospects in scintillation materials, optical fibers, photoluminescent materials, microwave applications, humidity sensors, magnetic devices, catalysts and corrosion inhibitors, and have become a hot research topic in recent years. In addition to the above-mentioned application potential, barium tungstate nanomaterial is also a good photocatalyst for the degradation of organic pollutants under light irradiation.

Tungsten carbide coating by plasma spraying is mainly used for anti-sliding friction, vibration friction, wear resistance and corrosion protection of aero-engines below 500 ℃. It has been widely used in aero-engines at home and abroad.
