“…Chen et al [7] investigated the impact of hydrofluoric acid (HF) concentration in the etching solution on etching efficacy and found that the morphology of the channel could be altered by manipulating the proportion of HF present in the etching solution. Saraf et al [8] identified that the surface roughness after etching was greatly influenced by the etching duration and etching solution composition, rather than temperature, which had a negligible impact. Agrawal et al [9] used FeCl 3 to etch 304 stainless steel and found that the surface roughness and the nonuniformity of the flow path edge increased with the increase of etching time.…”

T The chemical etching method has the advantages of high precision and low cost for the preparation of steel surface microchannel, but the composition of the etching solution and the etching process have a great influence on the precision of the microstructure. In this paper, the influence of etching solution composition and the etching time on the etching precision of stainless steel using a mixture of HCl and H2O2 as an etching solution was studied. The reactions and passivation processes that occurred during the etching process were analyzed. The etching mechanism was revealed. The sample prepared with HCl:H2O2=1:2 can obtain better etching precision and high dimensional stability. The amount of lateral erosion and the depth of etching increased with the increase of etching time, resulting in a decrease in the etching factor and precision. Pitting and intergranular corrosion mainly occurred during the etching process, and the loss of metal chloride formed in the process would form holes, which would become rapid diffusion channels for corrosive Cl and O elements, and promote the etching process. The etching reaction formed a passivation film on the surface of the substrate, which reduced the rate of the etching reaction.This article is protected by copyright. All rights reserved.

The implantation of stents and instruments with capillary action demands super-finished internal surfaces of the manufactured product. Elasto-abrasives magneto-spiral finishing (EAMSF) enhances the productivity of finishing by incorporating the abrasive flow in spiral motion due to the presence of the magnetic field. Here, novel impregnated elasto-magnetic abrasive particles (IMPs) are used in a magnetic field-assisted environment to polish the inner walls of the workpiece. In EAMSF, magnetic force provides excess finishing pressure to the abrasives whereas the elasticity of the high impact polystyrene (HIPS) absorbs the excess force of the IMPs on the finishing surface. An indigenous mathematical relation taking into account the physics of process indicating material removal shows a close resemblance to the experimental results with an error percentage of 1.03 has been developed. The results of experimentation revealed that with 50% concentration of abrasives and a magnetic field density of 18mT yields, a superior surface finish with a Ra value equal to 0.053 μm and maximum material removal of 6.9 mg; while in the absence of a magnetic field, superior surface finish with a Ra = 0.266μm and maximum material removal of 5.4 mg is achieved. In the presence of magnetic field density, significant enhancement of material removal, surface finish, and burr removal is observed. Finishing of the surface at 50% abrasive concentration with a magnetic field represents regular finishing and the trench marks present in the original surface are removed after finishing.
