Investigations on machinability of Al2O3 reinforced Al6061 metal matrix composites
(Süleyman Demirel Üniversitesi Fen Bilimleri Enstitüsü Dergisi, 2016)
In this study, six different MMCs containing Al6061 matrix and Al2O3reinforcements with particle sizes of 32 µm and 66 µm and weight fraction of 10%, 15% and 20% were produced using the vortex method. Machinability ...

(2018)
Bu çalışmada soğuk haddelenmiş ve ardından galvanizlenmiş St 22 çeliğininkimyasal bileşimi, soğuk haddeleme öncesindeki sac kalınlığı ve mekaniközellikleri (akma ve çekme gerilmesi, % uzama) ile soğuk haddeleme ezmeoranının ...
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 ...
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 ...
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, ...
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 ...
Boride Layer Growth Kinetics Of Aisi H13 Steel Borided With Nano-Sized Powders
(Polish Academy Sciences, Institute Metallurgy & Materials Sciences, 2018)
Growth kinetics of boride layers in AISI H13 steel was investigated using the pack bonding method at temperatures of 1073, 1173 and 1273 K (800 degrees C, 900 degrees C and 1000 degrees C) for periods of 2, 4 and 6 h with ...
