With the continuous consumption of petroleum resources, the environment for oil exploitation is getting worse and worse, and the requirements for corrosion resistance and friction resistance of petroleum equipment are getting higher and higher. At present, the phenomenon of eccentric wear and corrosion is serious in the field of petroleum machinery. No satisfactory surface treatment technology can be applied to the surface treatment of petroleum machinery, which can simultaneously possess anti-corrosion, wear resistance and low cost.

In recent years, lead-containing materials are being gradually eliminated due to their high pollution, high toxicity, low strength and low efficiency. It is hoped that high-energy polymer composites with good processability will be developed to expand the application of metal materials.

As a traditional material, nickel-tungsten alloy has attracted much attention because of its many superior properties and some potential applications. Tungsten-nickel alloy electroplating has compact structure, high heat resistance, comparable to ceramics, wear resistance and oxidation resistance at high temperature, and good self-lubrication and corrosion resistance.

Bismuth tungstate nanometer is a kind of photocatalytic material with high efficiency, low toxicity and good stability. It is a typical Olivis oxide with perovskite-like WO₆ layer structure and narrow band gap (only about 2.80 eV). It can effectively remove organic pollutants in water by visible light photocatalysis. In the treatment of water pollution, Bi₂WO₆ nanometer is a typical perovskite-like oxide. It has important application value.

Bismuth tungstate is the simplest orivis oxide with narrow band gap (about 2.7eV) and can absorb part of visible light. This material has been used for photocatalytic degradation of organic pollutants, photocatalytic organic reaction and photocatalytic decomposition of water.

When pilots fly an aircraft, the weight and gravity of the ship will affect the safety, maneuverability and performance of the aircraft. It is essential to maintain a stable center of gravity for optimal control and compliance with flight safety standards.

Solid acid catalytic materials have attracted more and more attention because of their unique structure. Niobium tungstate, as a typical solid acid catalytic material, exhibits good catalytic activity, selectivity and stability in some organic synthesis reactions. In addition, due to its unique structure and physicochemical properties, niobium tungstate compounds have attracted widespread interest in piezoelectric, dielectric and thermodynamic aspects.

In recent years, with the high integration of super LSI, the use of materials with lower resistance as electrode materials or wiring materials has been studied. In such materials, high purity tungsten with low resistance, thermal and chemical stability is used as electrode materials or wiring materials.

Manganese tungstate (MnWO₄) crystal has tungsten-manganese iron structure and belongs to the direct bandgap semiconductor material. Because of its special optical, electrical and magnetic properties, it has been widely used in the fields of photoluminescence, optical fibers, scintillators, humidity sensors, magnetic materials and ferroelectric materials.

In recent years, lead-containing materials are being gradually eliminated due to their high pollution, high toxicity, low strength and low efficiency. High tungsten content materials are ideal substitutes at present. However, for metal materials, its processing difficulty is very high, which limits its application in some fields.
