Plazma elektrolik oksidasyon yöntemiyle alüminyum alaşımlarının kaplanması
























































ii
ABSTRACT
In this work, the wear resistance characteristics of three different Al-Si cast alloys with %5, %8 and %11 Si contents were exemined after spheroidising heat treatment and coating these alloys using Plasma Electrolytic Oxidation (PEO) method. SiC water proof paper and stainless steel were used as counterfaces in wear tests.
The wear resistances were increased at least 30 times when the materials were coated by PEO method. This increase is 128.9 times for %5 Si containing alloy, 72 times for %8 Si and 30 times for %11 Si containing alloy. It is observed that the wear resistance of PEO coatings is negatively affected by the augmentation of the Si content and increasing the Si content of the alloys causes a increase in the wear resistance of uncoated materials.
Keywords : Plasma Electrolytic Oxidation, Micro-arc Oxidation, Wear, Aluminium.

NITRIDING OF NONFERROUS METALS BY PLASMA NITRIDING METHOD ABSTRACT Ti6Al4V alloys are very attractive materials because of their biocompatibility and corrosion resistance properties. But application of titanium and its alloys are very low in mechanical engineering applications because of poor surface hardness and wear resistance. These problems can be overcome using such surface engineering tech...

ABSTRACT v Titanium and its alloys are widely used in biomedical applications because of their corrosion resistance and biocompatibility. Nevertheless, the use of these materials for implants creates sometimes problem because of their poor surface hardness and wear resistance. To improve the poor surface hardness and wear resistance of titanium alloys used for surgical implants undergoing w...
