liekkikovetus
Liekkikovetus is a term used in Finnish-language contexts to denote a flame treatment of a material surface. The word combines liekki, meaning flame, with koetus or testitila meaning treatment or testing. In practice, liekkikovetus refers to exposing a surface to a controlled flame with the aim of altering its chemical or physical properties, often to improve adhesion or prepare the surface for additional coatings.
The process is most commonly discussed in materials science and surface engineering. Through controlled flame exposure,
Methods and equipment for liekkikovetus range from handheld gas-flame applications to automated flame-treating rigs. Key variables
Applications vary by industry but commonly include metal finishing, glass and ceramic processing, and polymer surface
