The paper presents the effect of size and repetition process on silica blasting on the surface character of Medical Grade SS316L. In this study, topography and surface roughness of SS316L will be evaluated both using optical and stylus methods. Medical Grade SS316L was blasted using silica sand with a mesh size of 10-30 (then called K), mesh 40-60 (then called S), and mesh 70-90 (then called H). Silica blasting processes was carried out on the surface of Medical Grade SS316L at room temperature, 90° of nozzle direction, and 7 bar of nozzle pressure. The silica blasting process was carried out by varying the treatments of K, S, H, KH, and SH for 10 minutes each. The results show that roughness increases with the size of silica sand, moreover the repetition of the H process on the K and S (KH and SH process) will refine the surface roughness of the results of S and K processes but when compared to H is relatively coarse.
This work aims to reveal the effect of the stand of distance (SOD)during the abrasive water jet cutting processes of Material implant stainless steel 316L on its corrosion properties. Abrasive water jet cutting processes were conducted in 5 different SOD there are 1, 2, 3, 4, and 5 mm between the nose of the nozzle and substrate surface. After these processes, the cross-section of the substrate was evaluated on its corrosion character using the potentiodynamic polarization method under Cl based solution. This process was conducted at room temperature with an almost steady state condition scan using Ag/AgCl/KCl as the reference Electrode and Pt as the counter electrode. The Results show that the corrosion resistance decreased as the SOD increased.
Roughness and flatness are things to consider in metal coating and painting. Sandblasting is one method to get certain roughness on the surface of the material. Blasting that occurs in the process affects roughness, flatness, and deflection of the workpiece. The purpose of this study was to determine the effect of the sandblasting process on surface roughness and flatness in SS 304 stainless steels material using variations in feed rate and distance by applying a semi-automatic sandblasting process by controlling the nozzle motion. The spray feed rate variations were 20, 40, and 60 mm min−1 and the distance variations were 100, 200, and 300 mm. The results of the test show that the smaller the feed rate and the closer the spraying distance, the higher the roughness value and the greater the deflection that affects surface flatness. The highest value occurs at a feed rate variation of 20 mm/min and a distance of 10 cm with a surface roughness value of 1.268 µm and flatness with a deflection angle formed of 1.184° one-sided treatment. In spraying experiments on two sided, improved the surface flatness with the highest deflection angle that occurs at a feed rate of 20 mm/min and a distance of 10 cm with a value of 0.737°.
