What is the difference between nano ceramic coatings and ordinary coatings?

In modern industrial manufacturing, coating technology has become an important field, and its applications involve multiple fields such as mechanical engineering, aerospace, electronics, construction, and medicine. Coatings can not only improve the surface hardness of objects, but also increase their wear resistance, corrosion resistance, and fatigue resistance, so they have been applied in various fields.

With the development of technology, the application of nanomaterials is becoming increasingly widespread, among which nano ceramic coating technology is a new type of coating technology that has been applied. Unlike ordinary coatings, nanoceramic coating technology has multiple characteristics. Let's explore the differences between nanoceramic coating technology and ordinary coating technology from the following aspects.

1. Differences in process preparation

Nano ceramic coating technology is prepared through nano ceramic materials, while ordinary coating technology is prepared through ordinary coatings. Nano ceramic materials refer to ceramic materials with grain sizes ranging from 1 to 100 nanometers, which have characteristics such as high hardness, high wear resistance, and high corrosion resistance. The preparation of nano ceramic coatings requires some special chemical and physical preparation technologies, such as sol-gel method, high-energy ball milling method, electron beam evaporation method, etc. Ordinary coating technology uses traditional physical and chemical coating techniques, such as spraying, electroplating, immersion, etc.

2. Differences in material properties

Nano ceramic coatings have many unique material properties, such as high hardness, high wear resistance, high corrosion resistance, high permeability, and high thermal stability. These material properties make nanoceramic coatings have a very broad application prospect, with applications in industries, healthcare, and environmental protection. The material properties used in ordinary coating technology are relatively simple, mainly achieved through the chemical and physical properties of the coating to modify the surface of the object.

3. Different coating thicknesses

Nano ceramic coating technology has high permeability and can achieve very thin coatings, with a thickness generally ranging from a few nanometers to tens of nanometers. The thickness of ordinary coating technology is relatively thick, usually ranging from a few hundred nanometers to a few millimeters. Nano ceramic coatings have excellent corrosion resistance and wear resistance, especially in high temperature and high pressure environments, where the performance of the coating is even more outstanding.

4. Differences in coating costs

The preparation technology and material characteristics of nano ceramic coating technology determine its high cost, which is much higher than that of ordinary coating technology. However, considering the uniqueness and high performance of nanoceramic coating technology, its high cost also has certain rationality. In contrast, the cost of ordinary coating technology is relatively low, making it a more economical and practical coating technology.

In summary, both nanoceramic coating technology and conventional coating technology have their own advantages and applicable ranges, which need to be selected according to different application situations. Nano ceramic coating technology has material characteristics such as high hardness, high wear resistance, high corrosion resistance, and high permeability, and can be applied in various high-tech fields; Ordinary coating technology is more suitable for mid to low end coating processing, and the cost is relatively low.
