This paper reviews methods for texturing surfaces for tribological applications and presents some innovative methods that could make surface texturing more cost-effective. Possible texturing methods were identified and classified according to their physical principles. This involved identifying existing texturing methods and also led to proposals for new possible methods. Three innovative texturing methods with low cost and high texturing speed are then presented: (i) a simpler and cheaper version of photochemical texturing, (ii) maskless electrochemical texturing, and (iii) masking surfaces by ink-jet printing followed by etching. From these, maskless electrochemical texturing was the cheapest and fastest, but the minimum size of the texture features was the largest. Ink-jet printing followed by etching is an alternative that may potentially provide a good combination of cost and resolution, but the texturing time depends on the surface area. Then, an attempt was made to delimit tribological applications where the use of such processes could be beneficial, based on analysis of experimental results of their tribological evaluation. These showed that the methods proposed could be particularly suited for components with contact areas larger than the width of the texture features under either hydrodynamic lubrication or starved lubrication.

Abstract:This paper presents a new method of manufacturing 3D components by using Flow-Controlled Chemical Machining (FCCM). FCCM can be used for fabrication of 3D components using flow control set-up (or pattern) and suitable etchant. In this investigation, pattern used is perforated and having wettability which is made up of the cotton material. The pattern material has etchant resistant properties. During machining, the pattern is placed on a workpiece and etchant is passed over the pattern. Due to wettability of pattern, a thin layer of etchant is formed below the pattern and etching of work piece is done in the direction of pattern in a stepwise. This investigation is useful in fabrication of various 3D free-form surface components. Since, the chemical etching processes have a very low material removal rate; by optimizing machining parameters such as flow rate of etchant, etchant concentration, temperature etc.; machining rate can be improved.

Abstract:Undercut plays a crucial role in the industry of photochemical machining technology. This paper inspects the effect of undercut on the process parameter in Photochemical Machining (PCM) of SS304. A full factorial (3 3 ) Design of Experiments (DoE) were performed consisting of twenty-seven experimental runs. The concentration of etchant, temperature and time of etching were assumed to be the control parameters whereas the undercut (Uc) was considered to be the response parameter. Analysis of Variance (ANOVA) technique was used to analyze the effect of control parameters on undercut and thus the evaluation of its optimal conditions were performed. The experimental investigations revealed that the temperature of etchant and time of etching are the most substantial factors affecting the undercut.
