Abstract
This research aims to determine the effect of pressure on the thickness of the DLC layer using the PCVD method on annealed AISI 410 steel and to determine the effect of pressure on the thickness and hardness using the PCVD method on annealed AISI 410 steel. In this research, the material used, namely AISI 410 steel, was heat treated using a temperature of 850°C with a holding time of 20 minutes. The technique used is DLC with the PCVD method using a mixture of argon plasma and acytylene gas. Then SEM-EDS testing was carried out referring to the ASTM E986 standard and Vickers method hardness testing referring to the ASTM E384 standard. From the SEM-EDS test results, the average layer thickness at a pressure of 1.0 mbar was 12.353 µm, 1.2 mbar was 12.997 µm, 1.4 mbar was 15.213 µm and 1.6 mbar was 15.493 µm. So it can be concluded that the higher the pressure, the layer thickness will increase. From the hardness test results, it can be seen that the highest hardness value in the sample with a pressure variation of 1.6 mbar has a Vickers hardness value with an average of 575.68 VHN. Meanwhile, the lowest hardness value was obtained in the annealed AISI 410 steel sample which had an average Vickers hardness value of 241.5 VHN. In the pressure range tested, the greater the pressure, the higher the hardness.
