Tribology could have an impact on factors such as the selection of materials, special structural design, lubrication, metal matrix composite, surface engineering, reducing the weight of the component. To improve tribology properties, surface engineering is one effective and flexible way handled by many industries [12]. Surface engineering has gained a lot of interest in recent years because of the production of low wear and friction phenomena. Modern surface engineering is seen in various industrial areas such as automotive, aviation, power engineering, medical engineering, micro-systems technology, microelectronics, etc. [13]. Surface engineering approaches are mainly used to optimize surface attributes and bulk materials. Surface coatings and surface treatments are two main components of surface engineering. Surface engineering can modify the surface properties like residual stresses, friction coefficients, surface hardness, wear, surface roughness, wettability, and corrosion rate (Figure 10.1).

Surface engineering is the process of modifying a surface of a component to induce enhanced properties to the component. There are two main categories of surface engineering: (1) surface modification and (2) surface coating. Surface engineering processes basically modify the microstructure and composition of the surface of a component, thereby improving the various surface-dependent engineering properties [3].

In [69], according to the analysis of studies published in [70–88], it was shown that the metals aluminium, magnesium and titanium, as well as alloys based on them, due to their low weight, are preferred for use in the spectrum of applications for which they are critical high performance and excellent combination of specific properties. The wider use of these materials in the aerospace, automotive and biomedical industries requires a significant improvement in their surface properties. Surface engineering is an economical and viable method for improving the surface properties of a material, such as hardness, wear resistance, and corrosion resistance, fatigue strength and oxidation resistance. Among the various methods of surface modification, high-energy processes based on the use of pulsed beams are very promising. Such methods include laser beams, plasma flows, powerful ion beams and electron beams.

It is an established fact that surface engineering that is tailored towards the coating and modification of metal surfaces is becoming increasingly important because it allows both the physical and mechanical properties of the materials to remain unchanged while at the same time the corrosion resistance is improved (Basavanna & Arthoba, 2014; Popoola, Aigbodion, & Fayomi, 2016a). Zinc and its alloys, due to their better corrosion resistance property, are commonly used in steel coatings. Although excellent in this mode of protection, but these coatings are often less durable when subjected to environments of combined wear and corrosion due to their intrinsic relative softness and ductility (Popoola, Aigbodion, & Fayomi, 2016b; Popoola & Fayomi, 2012). One good way of combating the durability challenge of these coatings is through co-deposition of inert particles on the zinc and zinc-alloy matrix (Popoola et al., 2016b; Tuaweri, Adigio, & Jombo, 2013).

Some of the surface engineering techniques include surface coatings, heat treatments, micro arc oxidation, etc. Friction stir processing (FSP) is one of the efficient surface engineering techniques that process the material in solid state with no or little residual stresses [7,8]. In this process, the material is processed by traversing an axially loaded rotating tool over it. The schematic of FSP is shown in Figure 1. During FSP, the microstructural evolution depends on the induced strain and the thermal cycles. The heat transfer and material flow depend on tool rotation speed (TRS), tool traverse speed (TTS), tool geometry, backing plate temperature and cooling rate post FSP process [9–11].
Modeling and monitoring methods for spatial and image data
Published in Quality Engineering, 2018
On a different scale, a similar synergistic effect between advanced manufacturing processes and novel solutions for dimensional metrology is observed at the micro-scale level for engineered surfaces (Malshe et al. 2013). Although not covered in this contribution, surface manufacturing and metrology will play an important role in many application domains of engineering in the near future. In fact, appropriate surface engineering can greatly affect many different functional performance (friction and wear resistance, hydrophobicity, hydrophobicity, osseointegration, etc.).
