Experimental Investigation on Tribological Behaviour of Various Processes of Anodized Coated Piston for Engine Application

Abstract

In the automobile sector, pistons are anodized on the crown, on ring grooves, and also on skirts to improve its wear resistance and corrosion resistance properties. In this work, we have carried out crown anodizing along with skirt anodizing simultaneously to study the wear resistance of anodized samples. The surfaces are anodized with three different processes such as soft anodizing, hard anodizing, and microarc oxidation (MAO) or well known as plasma arc oxidation (PAO). All the three processes differ in their respective procedures. The hardness value and microstructure of all the samples were tested to find wear resistance values and the effect of coatings on the samples. In wear testing, piston samples are rubbed on cast iron to denote its wear resistance based on weight loss per unit time. Reciprocating wear testing is also carried out on every sample for testing their wear resistance value.

Experimental investigations of heat ageing with chemical modification of hemp fiber elastic characteristics

“…Every polymer object's mobility is reduced by crosslinking. When compared to certain other samples, the fibre that matured over 5 days at 60 °C showed good physical qualities 16 . The very same specimen may be utilised to make more stable composites.…”

Mechanical evaluation of coir/kenaf/jute laminated hybrid composites designed for geotechnical uses

“…The toughness behaviour of coir, kenaf, jute, black framed, and composite materials are depicted. Jute/epoxy hybrids had a maximal Shore-D toughness 99, equivalent to Kenaf/Jute/Epoxy and Coir/Kenaf/Jute/Epoxy biocomposites 12 . The maximum toughness of a Kenaf/Epoxy combination was 89 Shore-D.…”

Experimental Investigation on Mechanical Properties of Glass Fiber Hybridized Natural Fiber Reinforced Penta-Layered Hybrid Polymer Composite

“…is sample's tensile strength was 101.65 MPa with a strain of 30.56%, which was much lower than the GJBJG sample's tensile strength. is is owing to the lower strength, higher cellulose content, and lower elongation percentage of bamboo fibers compared with jute fibers [13]. As shown in Figure 3, the composite failure is slightly less catastrophic in this situation.…”
