Load-dependent power loss is a major contributor to power loss in gear transmission systems. In this study, pin-on-disc frictional and FZG efficiency experiments were conducted with powder metallurgy (Distaloy AQ ? 0.2 %C) and wrought material (16MnCr5) combinations. The gear mesh torque loss from gear efficiency tests and the friction coefficient from the pin-on-disc tests were then compared. ...

Coating is one of the innovative approaches used to improve the wear resistance and load-carrying capacity of surfaces in rolling-sliding contact, such as gears and rolling element bearings. In this study, the tribological performance of standard gear material (EN 16MnCr5) and two kinds of powder metallurgy (PM) gear material (Distaloy AQ + 0.2% C and Astaloy 85Mo +0.2% C) with and without trib...

Machining operations are involv3ed in many manufacturing industries. Turning process is one of the most fundamental cutting processes. Cutting used in metal cutting. Surface finish and dimensional tolerances are used to determine quality of product and are the important quality attributes of turned product. In the present paper of investigation the experimental work has been employed for the op...

Abstract 16MnCr5 steel parts were additively manufactured by laser powder bed fusion in order to investigate the effect of microstructure on electromagnetic properties. As process parameters have a direct impact obtained microstructure, different conditions used manufacture samples which magnetic and electrical tests conducted. The results presented discussed terms density, Finally, correlation...

Accuracy and topography are significant indicators of precision machined high-quality surfaces. Case hardened steel (16MnCr5) was analyzed to obtain information about the effects technological data connections between accuracy (roundness) roughness parameters (Sa, Sz, Ssk, Sku). It found that feed rate has a influence on roundness parameters, there strong relationships these parameter values: c...

Abstract Typical high-strength products are made from carbon-rich steels possessing relatively high carbon content, thus reducing weldability. In this work, preliminary studies on designing and tailoring a low-alloyed steel for the laser-based powder bed fusion (PBF-LB/M) process by adding black (C) nanoparticles tungsten carbide (WC) particles enhancing material properties provided. First, bas...
