Surface modification of polyethylene by Ag+ and Au+ ion implantation observed by phase imaging atomic force microscopy
(Elsevier, 2012)
High density polyethylene (HDPE) has been modified by Ag+ and Au+ ion implantation with the energy of 60 and 200 keV, respectively. The doses of implanted silver and gold ions were as follows: 1 x 10(15), 5 x 10(15) and 1 ...
Testing of intergranular and pitting corrosion in sensitized welded joints of austenitic stainless steel
(Serbia : Association of Metallurgical Engineers of Serbia, 2017)
Pitting corrosion resistance and intergranular corrosion of the austenitic stainless steel X5Cr Ni18-10 were tested on the base metal, heat affected zone and weld metal. Testing of pitting corrosion was performed by the ...
