The methanol engine, as an environmentally friendly and energy-saving engine type, has a number of points, including the use of clean energy, the emissions are only water vapour, which is harmless to the environment, and the calorific value of methanol is higher than that of transmission fuels, which makes combustion more efficient and can effectively reduce fuel consumption. This type of engine is highly compatible with the concept of green, low-carbon and high-quality development, reflecting the importance of environmental protection and energy saving.
PVD coating technology, as an advanced coating process, has the advantages of lowering the temperature of the substrate, high hardness, good chemical stability, etc. It can prevent high-temperature corrosion, extend the service life of hot-end parts, increase engine power and reduce fuel consumption. This technology has been applied in the design requirements of aero-engine thermal barrier coatings. Through the self-developed high-energy ball milling preparation process technology, pre-pressure plus isostatic pressure moulding target billet technology, and low-temperature firing technology, a variety of ceramic targets with excellent performance are prepared to meet the design requirements of aero-engine thermal barrier coatings. This shows that PVD coating technology plays an important role in improving engine performance and reducing fuel consumption.
