In this research, the corrosion effect has been investigated on high-cycle fatigue lifetime and fracture behavior for heat-treated aluminum-matrix nano-clay-composite piston aluminum alloys. For objective, after fabricating stir-casted nano-clay-composite, standard samples were machined rotary bending tests performed. To study effect, some specimens corroded in 0.00235 % H2SO4 solution 200 h th...

We study laser irradiation behavior of multiwalled carbon nanotubes (MWCNT) and chemically modified graphene (rGO)-composite spray coatings for use as a thermal absorber material for high-power laser calorimeters. Spray coatings on aluminum test coupon were exposed to increasing laser irradiance for extended exposure times to quantify their damage threshold and optical absorbance. The coatings,...

This paper gives research results about commercial examination of aluminum alloy-based products according to industrial standards. Results of metallographic tests of extruded aluminum microstructure shown in this paper indice that irregular deformation of material leads to microstructure variations through certain zones of the product. That influences mechanical properties, and it can even be t...

In this paper, an attempt has been made to experimental investigation the machinability of aluminum metal matrix composite (LM13/SiC/15p) during continuous turning of composite rods using carbide inserts. Base matrix material is Aluminium LM13 reinforced with 15 % weight by volume of Silicon carbide particles of mean diameter 20 μm to 40 μm is used. The main focus of investigation is to determi...

The microstructure of Basalt matrix composite materials produced by pressureless aluminum melt infiltration at 950 °C was investigated. It is established that uniform elements distribution observed within the whole sample depth. Interestingly, content variation considerably matches hardness profile connected with alumina phase presence. Sample color changes during temperature treatment due to t...

The high energy ball milling technique permits production of composite powders suitable for application in thermal spray processes. Different milling systems are compared concerning their potential for production of composite powder feedstock for spraying processes. Hard phase materials like carbides or oxides are incorporated into various metallic matrices including light weight alloys based o...
