High temperature wear behavior of the surface-modified externally cooled rolls
(Elsevier, 2018)
Externally cooled rolls of a steel plant were coated using three different surface modification techniques, namely titanizing, boronizing and borotitanizing. The grown coatings were examined using optical microscopy, ...
A Comparative Study on the Effects of Different Thermochemical Coating Techniques on Corrosion Resistance of STKM-13A Steel
(Springer, 2018)
The corrosion resistances of three different thermochemical coatings (grown using titanizing, boriding, and borotitanizing treatments) applied to STKM-13A steel surfaces were investigated. The coatings were characterized ...
Dry sliding wear behavior of bonded hot-work tool steel at elevated temperatures
(Elsevier Science, 2017)
In the present study, the surface of AISI H13 hot-work tool steel was bonded with EKabor II powders using powder pack-bonding method. The process was carried out at 800,900 and 1000 degrees C temperatures for 2,4 and 6 h ...
Microstructure and mechanical properties of borided inconel 625 superalloy
(Universidade Federal do Rio de Janeiro, 2017)
The Ni-based superalloy Inconel 625 is extensively used owing to its high strength, excellent fabricability, good weldability and outstanding resistance to high temperature corrosion against aggressive environments. However, ...
Microabrasion Wear Behavior of Fast-Borided Steel Tooth Drill Bits
(Taylor and Francis Inc., 2017)
In this study, the surface of steel tooth drill bits (Ni-Cr-Mo based) was subjected to the solid-state boriding treatment with 10- to 50-nm nanoboron powder. Boriding processes were carried out at a constant temperature ...
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 ...
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 ...
Effect of thermal degradation on the properties and wear behavior of Cr−V−C composite coatings grown on ductile iron
(Elsevier, 2021)
The thermal fatigue behavior of chromium vanadium carbide (Cr - V - C) coatings and the wear of the coatings after thermal fatigue cycling was studied. The Cr - V - C coatings were grown on the surface of a ductile iron ...
