Abstract
Laser color marking of stainless steel has been in the
interests of different industries for some time. Still
wide use of the process is not seen on consumer products
which might be because of lack of their usability
information. Laser processing of stainless steel surfaces
creates an oxide layer on the surface. The thickness of
this layer defines how white light is reflected from the
surface. What in principle is only a thin oxide layer on
the surface can be seen as different colors by the
viewer. If this oxide layer is thick and solid it will
have good corrosion and wear properties. Consumer
products are constantly under certain corrosion and wear.
In this study, the corrosion and wear properties of laser
color marking on AISI Type 304L (EN1.4307) austenitic
stainless steel were evaluated based on laser process
parameters and colors. The results show that the
corrosion properties of marked surface expressed as
critical pitting temperatures (CPT) depend on heat input:
coarsely the lower heat input the higher CPT. Also
scanning velocity has a remarkable effect on CPT. The
laser color marking parameters have a significant
influence on the wear behaviour of both the surface
itself and that of the counter body surface. Laser color
marking has high potential to become a widely used
technique for product marking and decoration.
