description | AISI 410 stainless steel is widely used for medical equipments because of
its corrosion resistancy, but it doesn�t have a high hardness value. Surface
modification is a method to improve the surface characteristics of the material,
such as hardness, wear and corrosion resistancy. The application of titanium
nitride (TiN) as a thin layer will improve the properties of AISI 410 stainless steel,
as TiN has high hardness, high chemical stability and good adhesion bonding
with the substrate. This study aim at studying the effect of a TiN thin layer that
deposited by DC magnetron reactive sputtering on surface of AISI 410 to
hardness, corrosion rate, abrasive wear and roughness.
The deposition process used a DC magnetron sputtering machine with
constant variables are current of 80 mA, voltage of 0,4 kV, chamber pressure of
4 x 10-2 torr, pressure ratio of Ti: N = 17:3, and substrate-specimen distance of
12 mm. The experiment was carried out by varying the deposition time of 30, 40,
50, 60 and 70 minutes. The hardness test used a micro-Vickers hardness tester,
the corrosion test used a galvanostat PGS 201T with testing media 0,9% NaCl,
the abrasive wear test used an ogoshi high speed universal wear testing machine
OAT-U and the roughness test used a surface roughness instrument SE 1700.
The results of this study indicate that the hardness value will increase with
longer deposition time and then its decrease after reaching the highest hardness,
where the highest hardness value is obtained at the deposition time of 50 minutes
with an average hardness value 245,28 VHN0,01. The corrosion rate and abrasive
wear will decrease with longer deposition time and then its increase after
reaching the optimum conditions. The lowest corrosion rate and the lowest
abrasive wear are obtained at the deposition time of 50 minutes, with the average
corrosion rate is 2,2 mm/yr and the average abrasive wear is 2,6 x 10-6mm3/kg.m.
The roughness value does not show a significant difference between the raw
material and the AISI 410 stainless steel which has been deposited with TiN. |
