Textiles

Thermally sprayed coatings have been used successfully against wear on textile machinery for years. In particular plasma spraying is used to deposit ceramic coatings that can be matched to specific requirements and finished to required surface textures.

 

Considerable abrasive wear is often the cause of worn components, for example, high rotational speed of grooved rollers results in considerable abrasion wear which is seen as an increase in the groove diameters. Due to the very high rational speed, the roller has to be made from aluminium and therefore, the reduction in wear can only be achieved by the deposition of a coating. Alternatives such as plating are often unsuitable due to the smooth, non-structured surface leading to poor co-efficients of friction.
