The current work focuses on effects of double side peening on metallic card cutting doffer wire. The doffer wire commercially procured was subjected to double side peening with and without the sacrificial layer. The commercially available black paint was used on the doffer wire .The effect of laser peening on surface roughness, residual stress, hardness and micro structure were analyzed. The surface roughness was found to be 2.574 μm which was only a 15% increase in value 2.209 μm. The value of residual stresses, for the upper and bottom surfaces of the doffer wire used in the study were -185.7 MPa and -147.7 MPa, respectively. The hardness of the double-side peened samples with and without coating increased by 11.7% and 9.85%, respectively. Optical microscopy studies reveals that the formation of carbides increased the hardness of the doffer wire.
The purpose of road pavement is to provide vehicles with a uniform running surface that has a high skidding resistance, strong against rutting, fatigue and durable too in all-weather condition for its design life. To meet the increasing demand for performance, a variety of additives used for enhancing the properties of bituminous mixtures. In this present research work, the main objective is to understand the engineering properties of the Bituminous Concrete (BC) mix with and without fiber. Two types of fibers are used in this study along with conventional mix, namely polyester and pelletized cellulose fiber. For preparation of the mixtures, aggregate gradation was adopted from MoRTH specifications, binder content has been varied regularly from 4.5% to 6.5% and fiber content 0.1%, 0.3% and 0.5% of total mix, the optimum fiber content was obtained at 0.3% from stability and volumetric analysis.
Biomaterials plays a significant role in the biomedical sector (orthopedic implant) application to solve the problems related to material selection. The metals and alloys are widely used in a biomedical implants due to its key merits such as high mechanical properties, ease of manufacturing, reasonable biocompatibility, high fracture resistance, reliable long-term implant performance in major load-bearing cases, etc. When metallic materials are used in corrosive human body conditions, their degradation occurs, which is a major concern for biomedical engineers. Therefore, knowledge of the different types of biomaterials, their properties, problems and considerations for the choice of metallic biomaterial described in this study is very important for future researchers.
This study is focused on degradation of Amaranth (AR) dye, mainly with the parameters like effect of oxidant concentration, ferrous ion concentration, pH of the initial solution, iron powder (Fe0) concentration and different iron salt which are the primary source of Fe2+ ions. The degradation of AR dye in different remediation processes including Fenton process, photo-Fenton process and Fenton's type process were investigated. The examined Vis/APS/Fe0 process was found to be very efficient for discoloration. The study also evaluated the degradation of textile effluents. The process showed good characteristic, which can make it an effective alternative for polluted aquatic system remediation. Advanced oxidation process utilizing Fenton's reaction was investigated for the decolorisation and degradation of commercial dye Amaranth dye and concluded that the initial oxidation reaction was found to be fit into pseudo-first order kinetics.
Aggregate of more than one constituents (can be micro or macro) that diversify in form or chemical composition and are typically insoluble in each other, are called composite materials. In automobile industry, the metal-matrix composites have become a highly important materials due to its light weight and high strength properties. Different ceramic particles and solid lubricating materials were assimilated into aluminum metal-matrix to accomplish in both fatigue and wear resistance. Composites with aluminum matrix and non-metallic reinforcements are much familiar for extensive corrosion resistance, excellent machinability, wear resistance, fatigue strength, high thermal conductivity, etc. Reinforcement materials like particulate silicon carbide (SiC), graphite (Gr), molybdenum disulfide (MoS2), titanium carbide (TiC), alumina fly ash etc., can easily be assimilated in the molten metal-matrix using low priced and widely available stir casting method. This paper presents a review on ramification of reinforcement on stir casting of aluminum metal-matrix composites (AlMMC) containing single and various reinforcements.
