Article
Full-text available
The hybrid method of three-dimensional ion implantation and electric arc is presented as a novel plasma-ion technique that allows by means of high voltage pulsed and electric arc discharges, the bombardment of non-metallic and metallic ions then implanting upon the surface of a solid surface, especially out of metallic nature. In this study AISI/SA...

T he three-Dimensional Ion Implantation technique (3DII) causes ions to collide with a solid surface in a perpendicular way regardless of the geometry of the solid (Khvesyuk & Tsygankov, 1997; Dougar-Jabon, Dulce-Moreno & Tsygankov, 2002). The steel AISI SAE 4140 has been used as substrate because of its wide use in the transport of oil industry, t...

Question
hello everyone, I am looking for a way to sterilize porous disks of nano hydroxyapatite, I only have autoclave available so was thinking of putting the hydroxyapatite in polypropylene flask with polypropylene loosen caps all that inside the autoclave and once the cycle is finished  quickly close the caps... what can someone please recommend? i need to transport the disks samples in sterile condition, not able to move the autoclave neither can find an autoclave in the destination. Thanks in advance. 
Question
I have not enough samples to perform mechanical testing on 7075 aluminum alloy with T6 and several agings and retrogression aging treatments, so, I am looking for a way to obtain an approximation of mechanical properties extrapolating hardness or micro-hardness measurements.
Question
I have a set of samples, bio-ceramic coating on 316L SS, and I need to measure the adhesion of the coating, I'm looking for someone interested in doing that test.
Question
I have a picture from SEM. I want to measure a length in nanometers, and wonder if any free software can do it?
