Introduction Hydrogen embrittlement and brittle fracture of materials are occurred by hydrogen diffusion which is important phenomenon.
As a result, coupled mass diffusion with stress phenomena occurred by hydrogen diffusion causes some problems for materials like, embrittlement, degradation, crack assisting and finally fast fracture and consequently, material will be failed.
As a result, science of materials and profound mechanical studying of a micro structure in experimental method illustrate the procedure and mechanism of diffusion, degradation, and embrittlement and fracture to some extent but not completely [9, 10].

In addition, to bring some factors into account such as the thickness of nickel substrate and grit of CBN abrasives, the certain amount of material should be removed from the matrix.
In gear-honing with plated CBN honing wheel, cutting depth is related with radial force of honing tooth, normal pressure angle at pitch circle, contact points of homonymous teeth, material's elastic modulus, Poisson's ratio and other factors; 5.

Tribology is the science and the technologies of interacting surfaces in a relative motion.
One of the most important information sources is having the results of ferographical analysis (a type, a size, material composition, distribution, morphology, speed of generation, etc.) and particles wear in real time, or lubrication oil degradation obtained by using the methods FTIR (Fourier Transform using Infra-Red light), etc.
Modifying the maintenance will help to reduce manpower, save time, energy and material.
