Boron determination in steels by Inductively-Coupled Plasma spectometry (ICP) [PDF]
, 1985 The sample is treated with 5N H2SO4 followed by concentrated HNO3 and the diluted mixture is filtered. Soluble B is determined in the filtrate by Inductively-Coupled Plasma (ICP) spectrometry after addition HCl and extraction of Fe with ethyl-ether.

Advanced Engineering Materials, EarlyView.The wettability of aluminum droplets (Al) on different copper substrates (Cu), where liquid Al spreads on solid Cu surfaces to form a liquid–solid interface, is studied numerically and experimentally. The experimental and numerical results show good agreement in the fast‐spreading regime.

Advanced Engineering Materials, EarlyView.The subject of this work is the development of a corrosion‐protective coating on steel sheets for form hardening. Rapid heating in an extreme high vacuum (XHV)‐adequate atmosphere is a useful method to prevent oxidation during alloying of 22MnB5 and aluminum to obtain a metallurgical bonding.

Effect of boronizing composition on hardness of boronized AISI 1045 steel
Materials Letters, 2020 Abstract Surface hardening process of cam shafts manufactured from AISI-1045 Steel was provided by boronizing in liquid and solid media. To boronize in liquid and solid medium, various chemical agents were used. At this study, research was conducted on hardness and thickness of the layers obtained according to the boronizing composition.

Characteristics of Boronized 316L Austenitic Stainless Steel by Powder Boronizing [PDF]
Journal of the Korean institute of surface engineering, 2011 In this study, the mechanical properties of boronized 316L austenitic stainless steel have been investigated. Boronizing was carried out in solid medium consisting of Ekabor powder at 900 C and 1000 C for 2, 4 and 8 hours, respectively. The properties of sample were analyzed by field emission scanning electron microscope, X-ray diffractometer, Glow ...
