“…Active NoCE of 0 means circular symmetry, and hence the conical and spherical tips are commonly used for exploring the effect of crystal anisotropy on the values of critical load/depth of DBT and the friction coefficient [153][154][155]. Several representative experimental studies are listed in table 3.…”

Brittle materials are widely used for producing important components in the industry of optics, optoelectronics, and semiconductors. Ultraprecision machining of brittle materials with high surface quality and surface integrity helps improve the functional performance and lifespan of the components. According to their hardness, brittle materials can be roughly divided into hard-brittle and soft-brittle ones. Although there have been some literature reviews for ultraprecision machining of hard-brittle materials, up to date, very few review papers are available that focus on the processing of soft-brittle materials. Due to the “soft” and “brittle” properties, this group of materials has unique machining characteristics. This paper presents a comprehensive overview of recent advances in ultraprecision machining of soft-brittle materials. Critical aspects of machining mechanisms such as chip formation, surface topography, and subsurface damage for different machining methods, including diamond turning, micro end milling, ultraprecision grinding, and micro/nano burnishing, are compared in terms of tool-workpiece interaction. The effects of tool geometries on the machining characteristics of soft-brittle materials are systematically analyzed, and dominating factors are sorted out. Problems and challenges in the engineering applications are pointed out, and solutions/guidelines for future R&D are provided.

“…In this study [46], the TEM specimens were carefully prepared by cutting and grinding, followed by ion beam thinning using a precision ion polisher and electron beam was parallel to the scratching direction to avoid any possible damage. Characterisation of the sublayer damage of soft-brittle materials apparently needs more research efforts [47].…”

“…The mechanical strength of the Repellix deposit was also characterized through nanoscratch. Nanoscratch is a useful method for investigating the nature of wear, fracture, and friction in material remover mechanisms [23]. The coefficient of friction and the penetration details acquired from the tests are presented in Figure 2.…”

There is an increase in demand for durable and efficient organic nanoscale coatings for modern manufacturing systems and/or components for various applications. In wake of this demand, a new superhydrophobic silane compound was deposited on mild steel, stainless steel and titanium substrates which were pre-treated with alumina via the atomic layer deposition (ALD) method. Three substrates were considered for evolving properties comparison, also, determination of the influence of substrates’ response to films mechanical properties. The mechanical properties and the failure mechanics were investigated through nanoindentation and nanoscratch while the morphologies were examined through a field emission scanning electron microscope. The morphological evolution and mechanical viability indicated that stainless steel showed the most robust properties when compared with other substrates. Therefore, a nanoscale coating’s mechanical strength can be influenced by the substrate’s material compositions.
