Enormous usage of cutting fluid in industries is reporting the issues related to health employee, environmental pollution which promotes Minimum Quantity Lubrication (MQL). The study reports surface roughness modelling CNC turning under minimum quantity lubrication EN 24, taking into account effect environment, conditions using artificial neural networks (ANN). optimisation models are processed...

The study the hardness, wear corrosion resistance of as-coating, heat treatment and plasma-nitriding Ni- B electroless coatings was deposit on 4340 steel. After procees coating, samples were in percentage hydrogen/nitrogen ratio (50%), temperature 400°C, at 4 hours compared with treatment. characterization by FESEM, XRD, microhardness, Corrosion Resistance surface roughness measurements. Microh...

Due to their high strength and favourable mechanical behaviour, metals are used in a variety of applications within the automotive industry, including drive shafts. However, use metallic shafts sector presents some disadvantages such as inertial masses. This work investigates benefits using Carbon Fibre Reinforced Polymers (CFRP) for manufacturing A Formula Student car was model present design ...

This document describes the usage of Service Codes by the Datagram Congestion Control Protocol, RFC 4340. It motivates the setting of a Service Code by applications. Service Codes provide a method to identify the intended service/application to process a DCCP connection request. This provides improved flexibility in the use and assignment of port numbers for connection multiplexing. The use of ...

In this study, some mechanical properties of borided and unborided four steels were investigated. Boronizing of steels was performed by powder pack method at 1210 K for 4 h. The hardness of borides, boride layer thickness and room temperature tensile properties were measured and it was observed that hardness and tensile properties strongly depend on chemical composition of steels. In addition, ...
