Mechanical and gamma ray attenuation properties of N316L steel treated by rf plasma as a nuclear material
The effect of plasma surface engineering on average surface roughness, wettability and gamma ray attenuation properties of AISI316L standard steel sample were carried out. The results showed an increase in surface roughness accompanied with an increase in the surface energy and a decrease in the contact angle of N316L sample treated by plasma carbonitriding. The experimental measurements of gamma ray ... Read more
