Electrolytic boriding of powdered iron compacts

Metal Science and Heat Treatment, 1978
To obtain a thin boride coating with the maximum possible hardness on iron compacts and monolithic Armco iron. electrolytic boriding should be conducted at 950±10° for 1–1.5 h in an electrolyte consisting of 49%B2O3+34% Na2B4O7+17% B4C.

Complex iron-boride coatings on titanium alloys

Metal Science and Heat Treatment, 1986
1. The wear resistance of titanium alloys may be increased by applying a protective iron boride coating to them by the method of electrolytic deposition of iron followed by boriding. 2. The optimum distribution of hardness in the iron boride coating is achieved with inclusions of dispersed amorphous boron particles in an iron matrix ...

Thermodynamic Characteristics of Iron Subgroup Borides

Powder Metallurgy and Metal Ceramics, 2002
Standard enthalpies of formation and atomization Cpo(298.15 K), So (298.15 K), Ho (298.15 K) ― Ho(0 K) and the temperature dependence of the heat capacity in the range 298.15 K-Tmp have been determined for iron subgroup borides.

Seebeck coefficients of iron group elements borides

Intermetallics, 2004
Abstract In order to explore n -type borides-based thermoelectric materials, Seebeck coefficients of Fe–Co–B and Ni–Co–B materials were measured between 430 and 960 K. X-ray diffraction (XRD) patterns of Fe x Co 1– x B( x ⩽0.5) showed that FeB and CoB form solid solutions but their Seebeck coefficients were negative only at x =0 (i.e.

Plasma Silicon Nitriding and Iron Boriding

Journal of Vacuum Science and Technology, 1973
Plasma hardening of silicon and iron surfaces was investigated to determine if such processing can provide any advantage over conventional methods. In particular, can suitably hardened surfaces be achieved at lower temperatures or with shorter process times?

Photoelectron spectroscopic and thermodynamic studies of the formation of iron boride layers on pure iron substrates in powder boriding

Crystal Research and Technology, 1982
AbstractIn‐situ studies of chemical reactions and transport processes occurring in powderous rection media during the production of refractory layers on metallic substrates are impossible. However, results of the studies of the layers formed by means of suitable surface analyses, e.g. ESCA, combined with thermodynamic estimations permit these processes

Formation of iron boride layers on steel by d.c.-plasma boriding and deposition processes

Surface and Coatings Technology, 1999
Abstract Boriding and deposition of iron borides on Armco iron and the steels Ck45 and 42CrMo4 have been investigated at temperatures below 833 K using BCl 3 –H 2 –Ar gas mixtures activated by pulsed d.c. glow discharges. For the layer deposition FeCl 3 and Fe(CO) 5 were used as precursors.
