The influence of alloy sulfur on the crevice solution chemistry and the nature of the surface in the crevice during initiation were investigated. Two austenitic steels with different amounts of sulfur in the alloy, AISI 316L and SS 2343, were compared using electrochemical measurements with an addit ...

Dodajalne (aditivne) tehnologije oz. 3D tisk je proces izdelave, ki temelji na dodajanju materiala sloj za slojem in predstavlja nov način izdelave strojnih oz. konstrukcijskih elementov. Njeni začetki segajo v 60. leta prejšnega stoletja, danes pa je že tako razširjena, da nas spremlja skoraj na vs ...

Titan in njegove zlitine se pogosto uporabljajo v različnih industrijah (avtomobilski, letalski, farmacevtski …), saj imajo relativno nizko gostoto, visoko trdnost in dobro korozijsko odpornost. Izdelava titanovih polizdelkov in izdelkov po tradicionalnih tehnologijah je zelo draga, zato so za njiho ...

Titanium hydride powder, manufactured by ball milling titanium in a hydrogen atmosphere down to micron-sized particles, was analyzed by X-ray Photoelectron Spectroscopy (XPS). A strong titanium oxide signal was also measured, which decreased some what after intense sputtering of the sample, but was ...

Nepogrešljiva prisotnost kovinskih materialov v medicinskih aplikacijah je z najnovejšimi izzivi in trendi prehoda iz stalnih na začasne implantante bila razširjena tudi na raziskovanje biorazgradljivih kovinskih materialov. Glede na pomanjkljivosti prepočasne razgradnje zlitin na osnovi Fe, se doda ...

Additive manufacturing is a form of powder metallurgy, which means the properties of the initial metal powders (chemical composition, powder morphology and size) impact the final properties of the resulting parts. A complete characterization, including thermodynamic effects and the behavior of the m ...

AISI H13 is commonly used for tooling, where higher wear resistance, thermal fatigue resistance, or hot toughness is required. Such examples include forging dies, plastic molds, hot shear blades, high-pressure die casting, and extrusion dies. Thus, thermal conductivity is one of the most important f ...

A quantitative evaluation of the microstructure of aluminium foams and, particularly, any quantitative comparison is a very demanding and complex issue. In this work, the cell-size distribution (CSD) was proposed as the most efficient approach for their assessment. The foams were made by the powder ...
