Cyclic oxidation characteristics of HVOF thermal-sprayed NiCoCrAlY and CoNiCrAlY coatings at 1000 °C

Autor: M. Salehi Doolabi, S.K. Sadrnezhaad, Milad Rezaei, A. Feizabadi

Publikováno v: Journal of Alloys and Compounds. 746:509-519

Thermal-sprayed MCrAlY coatings have become widespread in various industries such as power plants, aeronautics, and oil and gas firms. High-temperature oxidation behavior of these coatings is therefore of significance. Spraying of two prevalent MCrAl

Hot corrosion behavior and near-surface microstructure of a 'low-temperature high-activity Cr-aluminide' coating on inconel 738LC exposed to Na2SO4, Na2SO4+ V2O5 and Na2SO4+ V2O5+ NaCl at 900 °C

Evaluation and Selection of Optimal Oxygen/Fuel Ratio for Best Mechanical Properties, Oxidation Resistance and Microstructure of HVOF NiCoCrAlY Coatings Using AHP–VIKOR Method

Autor: K. Jafarzadeh, S.K. Sadrnezhaad, Behrooz Ghasemi, M. Salehi Doolabi, Ali Habibolahzadeh

Publikováno v: Oxidation of Metals. 89:429-451

This work describes coating of NiCoCrAlY on IN-738LC superalloy by high-velocity oxygen fuel (HVOF) process. Properties of the coatings are significantly influenced by oxygen/fuel ratio and other spraying parameters. The effect of oxygen/fuel ratio o

Comparison of Isothermal with Cyclic Oxidation Behavior of 'Cr-Aluminide' Coating on Inconel 738LC at 900 °C

Autor: A. Feizabadi, M. AsadiZarch, D. Salehi Doolabi, S.K. Sadrnezhaad, A. Habibollahzadeh, M. Salehi Doolabi, Behrooz Ghasemi

Publikováno v: Oxidation of Metals. 87:57-74

A two-step pack cementation technique was used to cover nickel-based IN-738LC superalloy with a Cr-aluminide coating layer. The IN-738LC/Cr-aluminide samples were oxidized at 900 °C for 350 and 700 h, isothermally, and 175 and 350 h, cyclically. Eac

Influence of pulse parameters on electrocodeposition of Cr–Al2O3nanocomposite coatings from trivalent chromium bath

Autor: M. Salehi Doolabi, D. Salehi Doolabi, Mojtaba Asadirad, S.K. Sadrnezhaad

Publikováno v: International Heat Treatment and Surface Engineering. 6:178-184

Cr and Cr–Al2O3 coatings were electrodeposited from Cr(III) bath with both pulsating and direct current onto copper substrates. Pulsating current resulted in homogeneous films of higher Al2O3 content and lower particle agglomeration than the direct
