Microstructure, tribological behaviour and xrd analysis of hvof sprayed and laser remelted cocrtaalcsiy coatings

Superalloys with cobalt as a base material are widely used among different industry applications. Their main advantages are excellent corrosion and wear resistance. Material CoCrTaAlCSiY was chosen for this study as an unexplored representative of Co-based superalloys with a potential for go...

Influence of heat treatment on properties of SD251-PH1 composite produced by additive SLM technology

The aim of this case study was to evaluate how heat treatment affects the structure and properties of the engineered composite material labelled SD251-PH1. This composite material was formed by mixing two powder blends in a weight ratio of 90 wt. % WC-Co powder SD251 with...

Corrosion resistance of laser-deposited composite copper-basalt overlay

This paper deals with an assessment of the corrosion resistance of copper-basalt composite cladded by laser. The filler powder for laser overlaying was a mixture of high-purity copper powder Oerlikon METCO 55 consisting of 45–90 µm particles and a basalt powder comprising particles 50–2...

Revealing Hidden Orbital Pseudospin Texture with Time-Reversal Dichroism in Photoelectron Angular Distributions

We performed angle-resolved photoemission spectroscopy (ARPES) of bulk 2H-WSe2 for different crystal orientations linked to each other by time-reversal symmetry. We introduce a new observable called time-reversal dichroism in photoelectron angular distributions (TRDAD), which quantifies the modulation of t...

Promotional Effect of Manganese on Selective Catalytic Reduction of NO by CO in the Presence of Excess O-2 over M@La-Fe/AC (M = Mn, Ce) Catalyst

The catalytic performance of a series of La-Fe/AC catalysts was studied for the selective catalytic reduction (SCR) of NO by CO. With the increase in La content, the Fe2+/Fe3+ratio and amount of surface oxygen vacancies (SOV) in the catalysts increased; thus the catalytic ...
