Formation of iron sulfide photocatalytic colloidal dispersion via pulsed laser ablation in liquids

Pulsed laser irradiation of iron sulfide in water and ethanol allows laser ablation and generation of FeS nano/micro particles. Measurement of the size distribution reveals 100, 1000 and 5000 nm sized particles in water and 180 nm sized particles in ethanol. The values of ...

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...

Properties of Cryogenic Treated Cemented Carbides (WC-Co)

The present paper explores the effects of deep cryogenic treatment (DCT) on the properties of WC-Co cemented carbides. The investigation involved four different cemented carbide (CC) grades. Two of them were coarse-grained WC with grain sizes larger than 6 µm and binder fractions o...

Properties of Borided Cemented Carbides with Various Binders

This paper explores the thermochemical treatment of cemented carbides (CC), specifically the boriding process. Six different types of CCs with different size of tungsten carbide (TC) grains were chosen as experimental materials. They contained binders of different chemical compositions. In five&#...
