High purity solid graphite was used as a source cathode and purity titanium was used as the cathode materials.
Friction coefficient of Ti materials treated by hydrogen-free carburizing reduces by about 1/2.
From it, we can see clearly the alloy layer different from substrate materials on the surface of Ti after hydrogen-free carburizing.

Introduction Hydrogen-assisted mechanical degradation of structural materials is one of the most complex phenomena of the metallic materials degradation, due to several new unknowns in the degradation process kinetics, compared to the degradation in the absence of hydrogen in metal.
Hydrogen may degrade the mechanical behavior of metallic materials, including steel, and lead them to failure.

Introduction BFRP bar is made of multi-strand resin matrix material combined CBFS, via extruding and drawing, extrusion molding processes begin from the raw material, and then after soakage, pressing dies, curing, cutting, etc, and finally being a new composite material.
Using the opressive sleeve anchor developed by the researchers,tensile tests of BFRP bars are carried out [12].In test, let it cover the BFRP bars’ in end.Tensile test was done in building materials laboratory of Liaoning Technical University electric-fluid servo compression machines.It is shown in Fig.1.
From the above curve, its tension - deformation after peak intensity, similar to vertical drop.It is different from the steel which exist obviousyield stage.So BFRP bars belong to brittle materials.
