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, ...
Properties and Corrosion Resistance of AISI H13 Hot-Work Tool Steel with Borided B4C Powders
(Korean Institute of Metals and Materials, 2019)
Abstract: In this study, the surface of AISI H13 steel was borided with powder blends of B4C and NaBF4 using the powder-pack method at 800, 900 and 1000 °C for 2, 4 and 6 h. The structural and mechanical characteristics ...
Properties and High Temperature Dry Sliding Wear Behavior of Boronized Inconel 718
(Springer, 2020)
Silicide-free boride layers were grown on Inconel 718 Ni-based superalloy surface at 850 degrees C, 950 degrees C, and 1050 degrees C for 2, 4, 6 hour by the powder pack-boronizing process using nano-sized B4C powders. The ...
Properties and Corrosion Behavior of Chromium and Vanadium Carbide Composite Coatings Produced on Ductile Cast Iron by Thermoreactive Diffusion Technique
(ASME, 2020)
Ductile iron (DI) owes many of its attractive mechanical properties to the graphite nodules in its structure. However, since galvanic coupling can occur between the graphite nodules and the matrix in aggressive environments, ...
Properties and Corrosion Resistance of Borided AISI H11 Tool Steel
(Asme, 2020)
In this study, the effect of different boriding parameters on some mechanical properties and corrosion resistance of AISI H11 steel, which is extensively used in hot and cold processing applications, was investigated. The ...
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 ...
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 ...
Effect of Cr Addition on Properties and Tribological Behavior at Elevated Temperature of Boride Layers Grown on Borosintered Powder Metallurgy Alloys
(Korean Institute of Metals and Materials, 2022)
This study focused on chromium addition (0 wt%, 3 wt%, 6 wt%, 9 wt% and 12 wt%) on the boride layer formation, microhardness, fracture toughness and elevated temperature friction and wear behaviour of alloys formed by ...
Effect of boronizing on microstructure, high-temperature wear and corrosion behavior of additive manufactured Inconel 718
(Elsevier, 2022)
In this study, Ni-based Inconel 718 coatings were additively manufactured on the surface of AISI H13 work tool steel by electro-spark deposition (ESD). Some of the electro-spark deposited samples were boronized at 1000 ? ...
Powder-pack boronizing of CoCrFeNiAl0.5Nb0.5 HEA: Modeling of kinetics, microstructural, mechanical, and tribological characterizations
(Elsevier, 2022)
This study is dedicated to the detailed investigation of boronization kinetic, microstructural, mechanical, and wear properties of high entropy alloys (HEAs) considering their sluggish diffusion effect properties. A ...
