Abstract (Swedish)
Surface finish and surface integrity is important to produce high quality parts in the
manufacturing industry. This is controlled by properties on the cutting tools such as
edge radius, edge preparation, coating etc. Solid carbide tools are often coated with
PVD coating technologies where AlCrN is a common coating composition. Tooling
for small parts machining often creates issues with coating as the edges are precision
ground which reduces the adhesion of coating. Oerlikon Balzers new S3p coating
technology results in a smoother and pore-free coating.
The objective for this project is to make a comparison between S3p and arc vapour
deposition coating technologies. With focus on surface integrity of the coating and

Surface finish and surface integrity is important to produce high quality parts in the

technology results in a smoother and pore-free coating.
The objective for this project is to make a comparison between S3p and arc vapour
deposition coating technologies. With focus on surface integrity of the coating and
the influence of edge preparation. A series of machining tests will be performed in
AISI 316L and Ti-6Al-4V to analyze the performance and wear resistance of the
coatings.
The results include surface roughness on the deposited coating, generated surface
roughness on the test piece, coating thickness, edge radius measurements, and mul-
tiple identified issues with coating integrity and tool wear.
The S3p coating technology is performing in the same range as the conventional PVD
coating technology. For machining Ti-6Al-4V it showed an reduction in generated
surface roughness on the part and improved wear resistance. For machining AISI
316L an reduction of adhesion between the work piece and the insert was identified.
Edge preparation improved the deposited coating integrity by reducing droplets and
increasing adhesion as the edge radius increases. The Alcronos S3p coating has great
potential and by further improvement it can be a valid candidate for small parts
machining. (Less)
