Mechanical Properties and Corrosion Resistance of Borosintered Distaloy Steels
(Springer, 2020)
Distaloy SA is a sponge iron powder (nominal composition: Fe-1.75Ni-1.5Cu-0.5Mo) widely used in the production of powder metallurgy (P/M) parts in the automotive industry. In this study, Distaloy SA powders were sintered ...
Properties and tribological performance of ceramic-base chromium and vanadium carbide composite coatings
(Elsevier, 2019)
In the current study, the surface of AISI D2 steel was coated with the powder blends of ferro-vanadium (Fe-V) and ferro-chromium (Fe-Cr). The coatings were performed using a thermo-reactive diffusion (TRD) treatment by the ...
Microstructural and mechanical properties of friction stir welded pure lead
(National Institute of Science Communication and Information Resources (NISCAIR), 2018)
The present study focuses on the applicability of friction stir welding to pure Pb plates. The joint performances are evaluated by optical microscopy, microhardness measurements, notch impact tests and three point bending ...
Properties and High-Temperature Wear Behavior of Remelted NiCrBSi Coatings
(Springer, 2020)
Remelted NiCrBSi coatings were examined using optical microscopy, scanning electron microscopy, energy dispersive spectroscopy, x-ray diffraction analysis, microhardness and wear testing. After wear tests, the surfaces of ...
A new approach to sintering and boriding of steels "Boro-sintering": Formation, microstructure and wear behaviors
(Elsevier, 2020)
In this study, sintering and boriding methods are applied as a single step, and it is aimed to gain time and economic advantage. For this purpose, powder mixtures prepared in suitable compositions were subjected to sintering ...
Friction and wear behavior of epoxy composite filled with industrial wastes
(Elsevier Sci Ltd, 2019)
Waste utilization is an important alternative to reduce disposal costs, potential environmental pollution problems, decrement of natural resources and production costs. In this study, it is aimed to create a different usage ...
Characterization and wear behavior of TiBC coatings formed by thermoreactive diffusion technique on AISI D6 steel
(Elsevier, 2020)
A two-step Thermo reactive diffusion processes (including an initial titatinizing step followed by boronizing) is proposed in order to obtain superhard complex TiBC coating layer on AISI D6 steel. Microstructural ...
Effect of borotitanizing on microstructure and wear behavior of Inconel 625
(Elsevier, 2017)
Inconel 625, a nickel-based superalloy, is used in a wide range of applications including the marine and petroleum industries under where it is subjected to harsh conditions such as high temperatures and highly corrosive ...
Determination of Barreling of Aluminum Solid Cylinders During Cold Upsetting Using Genetic Algorithm
(UNIV FED RIO DE JANEIRO, LAB HIDROGENIO, 2019)
This study presents Genetic Programming models for the formulation of barreling of aluminum solid cylinders during cold upsetting based on experimental results. The maximum and minimum radii of the barreled cylinders having ...
Effects of blanking speed on the shear surface of mild steel (St37)
(Polish Academy of Sciences, 2016)
Blanking operation is widely used to cut sheet or plates by a shearing process between punch and die. The process of shearing and the conditions of the sheared surface are influenced by the punch, the die, the speed of ...
