“…The wear scar diameter generated when lubricating with phosphite based EP additives was however found to decrease linearly with increasing reaction starting temperatures. A similar observation was later made by Wan and Xue [26], who studied the performance of phosphorus based lubricant additives for lubrication of aluminum. They indicated that the tribochemical reaction between the EP additive and the sliding surface was initiated by a flash temperature generated in the rubbing action.…”

Punching and blanking processes are characterized by severe tribological conditions due to the creation of virgin surfaces, which are highly prone to develop pick-up of workpiece material on the punch surface. Hazardous forming lubricants are, therefore, commonly used in punching and blanking processes for avoidance of wear induced process deviations such as diminished surface quality, reduced dimensional accuracy and reduced tool life. The present study characterizes the function and performance of lubricants used for punching and blanking operations for assessment of the tribological lubricant properties necessary for adaption of environmentally friendly lubricant alternatives.Analysis of the tribochemical properties of the studied lubricants indicate that an applicable temperature range and a high load bearing capacity are central lubricant properties necessary for ensuring sufficient lubricating ability for punching and blanking operations.

“…Due to its premium qualities, Al alloys are having applications in automotive, aerospace industries, etc. (Bakes et al, 1979;Wan and Xue, 1996;Smagorinski et al, 1996). Metal matrix composites are a special combination of materials, which are having superior properties than alloys and pure materials (Budinski, 1988;Shafiei-Zarghani et al, 2009).…”

PurposeThe objective of the paper is to evaluate the fabrication process and to study the influence of process parameters of friction stir processing of 6061-TiB2-Al2O3 Aluminum alloy surface composite on microhardness tensile strength, and microstructure.Design/methodology/approachFriction stir processing method is used for attaining the desired mechanical properties, and selectively processed reinforcements to fabricate the samples. The Taguchi technique was used to optimize rotational speed, travel speed and volume percentage of reinforcement particles to enhance the mechanical properties of 6061-TiB2-Al2O3 Aluminum alloy composite.FindingsThe fabrication of surface composites through FSP allows new inventions in terms of material with enhanced surface layers without changing the base metal.Practical implicationsTo examine the behavior of the surface of the composites in the different zones, the practical implication consists of the use of different characterization techniques like optical microscopy and scanning microscopy for microstructural behavior and the measurement of hardness and tensile tests for mechanical behavior.Originality/valueThe research work consists of tool design and process parameters, which can affect the final product (microstructural changes), and the performance of the modified surface layer behavior was studied and presented.

“…However, these alloys are often reported to exhibit inadequate surface properties such as wear and corrosion resistance, and thus are often required to be replaced frequently [1]. It should be noted that developing the ceramic particle reinforced surface has been quite successful in addressing the poor wear resistance issues of aluminum alloys [2].…”

Effect of Laser Remelting and Simultaneous Application of Ultrasonic Vibrations during Laser Melting on the Microstructural and Tribological Properties of Laser Clad Al-SiC Composites

Laser composite surfacing of aluminum alloys with ceramic particles has been extensively investigated for improving tribological properties. However, the process often results in incomplete penetration of ceramic particles in the melt pool and undesirable interfacial reactions. In this paper, laser composite surfacing of 2024 aluminum alloy with SiC particles is investigated using two distinct approaches: laser remelting and laser melting under the influence of ultrasonic vibrations of preplaced powder mixture. Detailed analysis of variation of clad layer thickness, microstructure in the composite clad layer, phase/texture development, surface roughness, and sliding wear performance with laser processing conditions is presented. The analysis showed that remelting and ultrasonic vibration assist results in significant improvement in clad layer thickness and microstructure (reduction in needle-like α-Si phase). While the laser remelting resulted in significant reduction in wear rate, the specimens processed with ultrasonic vibration-assisted laser melting showed variable wear rate, likely due to complex effects of microstructural modification and enhanced surface roughness.
