For
years, thermal spray coatings have been used against
wear on textile machinery. Steel thread guiders, snick
pins and conditioning rollers use super fine - grained
threads and equipment.
Considerable
abrasive wear is often the cause of worn components,
for example, high rotation 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 coefficients
of friction. Advantages include
