“…As seen in Table 3, the activation energy of borided steel is affected by medium of boriding process [18,30,33]. While, the minimum activation energy is obtained by plasma-paste boriding for stainless steels of type AISI 304 with different mediums.…”

In this work, the kinetics o f the boride layers (FeB/Fe2B), formed on the X200CrMoV12 steel used fo r the cold-working, was investigated. The bonding treatment was carried out in the powder mixture consisting o f 5%B,C, 5% NaBF. and 90% SiC. The bonding parameters are : 900, 950 and 1000°C with treatment times o f 2, 4 and 6 h. The obtained bonded layers (FeB/Fe,B) were characterized by the following experimental techniques: optical microscopy, scanning electron microscopy coupled to EDS analysis and XRD analysis. The kinetics o f boron diffusion in the X200CrMoV12 steel was also studied. As a result, the time dependence o f the bonded layers thicknesses followed a growth parabolic law. The boron activation energy was estimated as 199.37 kJ m ol' for the X200CrMoV12 steel. A full factorial design with 2 factors at 3 levels was employed to estimate the total boride layer thickness as a function o f the bonding parameters (time and temperature) and a simple equation was proposed. Finally, an iso-thickness diagram was given as a tool to predict the total boride layers thicknesses in relation with the practical utilization o f this kind o f steel.

“…B 2 H 6 and BCl 3 gases have been used as boron source gases but were relatively expensive, toxic and explosive. Corrosion in the vacuum chamber and the formation of pores in the boride layer by boron chloride are other serious problems in plasma boriding [16,17]. These limitations on plasma boriding can be eliminated through plasma paste boriding (PPB) surface process.…”
