Karhennusmenetelmä
Karhennusmenetelmä, often translated as roughening method or surface preparation method, refers to techniques used to intentionally create a rough or textured surface on a material. This is typically done to improve adhesion between that material and another substance or coating. The increased surface area and mechanical interlocking provided by the rough surface enhance the bond strength compared to a smooth surface.
Common applications for karhennusmenetelmä include preparing metal surfaces before painting or plating, treating plastic surfaces before
Various physical and chemical processes can be utilized for karhennusmenetelmä. Physical methods include abrasive blasting (e.g.,
The effectiveness of karhennusmenetelmä is often evaluated by measuring surface parameters such as average roughness (Ra),
