Understand the different coating properties of the scraper：
1.Tungsten carbide coating: Through appropriate spraying processes, such as supersonic flame spraying, the tungsten carbide coating can form a firm bond with the base material, with high bonding strength and is not prone to peeling or falling off. This keeps the scraper in good protection over long periods of use .
2. Alloy coating: A layer of ceramic alloy coating is applied to the blade base. The thickness of the ceramic alloy coating is 100-500um, with high surface hardness and good wear resistance. It can reduce the friction and wear between the tool and the workpiece, thereby extending the service life of the tool.
3. Ceramic coating: This scraper is made by processing a steel sheet scraper. Its cutting edge is composed of a steel sheet scraper blade base, a nickel-aluminum alloy layer, and a ceramic coating. The nickel-aluminum alloy layer is directly coated on the blade base, with a thickness of 20-80um and a width of 6-14mm. A ceramic layer with a thickness of 130-300um is then coated on the nickel-aluminum alloy layer. This ceramic-coated scraper is wear-resistant and heat-resistant. Its service life is 7 to 13 times that of steel sheet scrapers, which can greatly improve the efficiency of papermaking production.
Iv. Summary
When choosing coatings, it is necessary to balance performance requirements and costs, for example:
Wear resistance first: Tungsten carbide or alloy coating;
Corrosion resistance first: Ceramic coating;
High-speed lightweight: Carbon fiber + thermal spray composite coating.
It is recommended to consult the supplier in combination with the specific working conditions and conduct coating performance tests (such as bonding strength and wear resistance tests) to optimize the selection.
