The paper presents investigation results and a technology for manufacturing fastener workpieces out of the 07Kh16N6-Sh (07Х16Н6-Ш) steel using high-temperature heat treatment. The steel undergoing our testing was additionally doped with molybdenum, as reflected in the 07Kh16N6M-Sh (07Х16Н6М-Ш) designation, which facilitated grain refinement. We implemented accelerated climate testing of bolts in order to assess the corrosion cracking resistance of 07Kh16N6-Sh (07Х16Н6-Ш), 07Kh16N6M-Sh (07Х16Н6М-Ш) and 13Kh15N4AM3-Sh (13Х15Н4АМ3-Ш) steel fasteners in maritime climates.

ABSTRACTThe diffusion of various dopants( B, P, As, and Sb) in (111) silicon during high temperature( 1100°C ) heat treatment in nitrogen depends on the capping layers, i.e., SiO2, Si3 N4, and SiO2 + Si3 N4, layers. The junction motion of all dopants were retar ed in the bare silicon compared with that in the SiO2 + Si3 N4 capped silicon. The apparently retarded junction motion of As and sb diffused specimens in the bare silicon is due to the severe out-diffusion loss of dopant atoms and As and Sb diffusion are in fact enhanced during thermal nitridation of silicon in N2.
