Structure and properties of chromium-nanodiamond composite electrochemical coatings

Elmas Nano Parçacik Takvi̇yeli̇ Krom Kaplanmiş Gözenekli̇ Toz Metal Parçalarin Korozyon Davranişlarinin Araştirilmasi

“…Isakov vd. [11], paslanmaz çeliği kromoksit asidik çözeltisinde elektrokimyasal nano elmas takviyeli krom ile kaplamışlar ve kaplama sırasında solüsyon içindeki nanoelmasların kaplamanın yüzey özelliğini değiştirdiğini görmüşlerdir.…”

Composite Coatings of Chromium and Nanodiamond Particles on Steel

“…By examining the surface morphology of the composite coatings of chromium modified with nanodiamonds with a scanning electron microscope (SEM) and an atomic force microscope (AFM) their grain refining has been proven [1,4,6] without clarifying the influence of the nanodiamond particles on the mechanism of the layer formation. By X-ray microanalysis the chemical composition of coating is determined and only presence of Cr in the layer is registered [1]. According to P.A.…”

“…Published literature essentially reflects the morphological changes of the surface and the increased values of microhardness and wear resistance of chromium coatings modified with nanodiamond particles [1][2][3][4][5][6][7][8]. The maximum increase of the composite coatings microhardness is about 2.5 times compared to the unmodified coatings [1][2][3][4][5][6]. Data on increased wear resistance at dry friction are quite diverse: 15% [2], 1.4-1.8 times [4] and up to 10 times according to the authors of the paper [8].…”

"Mechanical Alloying-Compaction-Electroplating" as Technological Scheme for the Development of Nanocomposite Coatings

“…Almost immediately after their discovery, nanodiamonds [5,6] began to be used for reinforcing electrochemical coatings [7,8].…”
