Multilayer coatings are used in a wide range of applications and can provide enhanced performance characteristics, such as improved wear resistance, reduced friction, and enhanced corrosion protection.
Among the various coating options for industrial blades available, tin (Sn) coatings have emerged as a popular choice, particularly for tungsten carbide blades used in plotter and cutter machines. Here are some of the advantages of using a tin coating on industrial blades.
The answer to that question depends on the benefit(s) you are looking for. If you are looking for extended blade life/reduction of change over time, or reduction of friction, a coating, or even a double coating could very well be worthwhile
Do I have to buy blades from the manufacturer of my machine? If you do not have a contract that explicitly stipulates that you do, for instance because it is a prerequisite for support by the manufacturer, than you don’t have to, and you can make use of generic blades or custom designed blades.
