Reinforcing pure titanium with 12 percent molybdenum and various weight percentages of zirconia increased the microstructure, mechanical properties, corrosion behaviour, and biocompatibility. To obtain a homogeneous distribution of Mo and ZrO2 in the titanium matrix, powder metallurgy is used. For the manufacture of composite powders, mechanical milling with a...

The research focuses on the effects of locally sourced carbonaceous materials such as Animal bone, Snail shell, and Periwinkle Shell on the mechanical properties of mild steel carburized at varying treatment temperatures of 700, 800, 900, 1000, and 1100 °C, soaked for 5hr, 4hr, 3hr, 2hr, and 1hr at...

The current research focuses on determining the physicochemical properties of brewery effluent and receiving water, which serves as a source of drinking water, fishing, and agricultural irrigation for the community. During the wet and dry seasons of 2016, the impact of brewery effluents on the water quality of the...

The method of assessing the crack resistance of coatings is discussed in this chapter. The influence of the substrate’s porosity on the coatings’ crack resistance has been proven. The approach based on the ratio between the crack length upon indentation of the Vickers indenter and the fracture toughness is...

To determine the absolute hardness of a film or coating, the contribution of the substrate must be separated. It is well known that the film thickness and the applied load are the two most important factors in determining the absolute hardness of a film in this circumstance. The contributions...

The surface modification of a titanium alloy via plasma immersion ion implantation was investigated in this study in order to increase its tribological qualities such as hardness and scratch resistance. Furthermore, the thickness of changed layers was investigated using physical simulation utilising SRIM (stopping and range ions in matter)....

Before and after depositing coatings of various metals, the structural, physical, and mechanical properties of aluminium after laser-induced shock peening (LSP) were examined (Cu, In, and Al). The physical properties (density), shockwave properties (shock pressure, particle velocity, and shock velocity), and mechanical properties (stress, strain, Young’s s modulus, and...

To understand the phase stability of ferrite at such elevated temperatures, duplex stainless steels with varying chromium content are taken and heat treated between the temperatures of 900 and 1000°C. Since the austenite grains remain unchanged after heat treatment, ferrite is the active step in duplex stainless steel. In...

This chapter focused on comparative studies on conventional, microwave and vacuum sintering of alumina-added stabilised zirconia yttria (YSZ). When energy and time savings are involved, microwave sintering has been found to be the most effective sintering technique. In contrast to the conventionally sintered ones, microwave and vacuum sintered specimens...

We present the findings of an experimental and theoretical investigation into the properties and characteristics of large-caliber precision slot cutting of low-carbon steel sheets up to 10 mm thick by 1 kW single-mode fibre laser radiation. Slots with calibres from 20 to 60 (in some cases, up to 100)...
