Journal of Boron

Bu çalışmada, AZ91 magnezyum alaşımı ve AZ91 alaşımına ağırlıkça %10 hBN (hegzagonal bor nitrür) ... more Bu çalışmada, AZ91 magnezyum alaşımı ve AZ91 alaşımına ağırlıkça %10 hBN (hegzagonal bor nitrür) nanoparçacıkları takviye edilerek homojen kompozit malzeme karışımları yapıldı. Hazırlanan tozların soğuk presleme yöntemiyle 400 MPa basınç ile preslenmesi ve 590 C° sıcaklıkta argon atmosferinde sinterlemeleri gerçekleştirildi. Hazırlanan numunelerin mikroyapıları taramalı elektron mikroskobu (SEM) ve enerji dağılımlı X-ışınları (EDX) analizleri ile incelenmiştir. Numunelerin 20 saniye yükleme süresinde 5 farklı noktadan sertlik değerleri alındı ve bu sertlik değerlerinin ortalaması alınarak ortalama sertlik değerleri belirlendi. Aşınma testleri pin-on-disk deney cihazında farklı yük değerlerinde (5 N, 10 N ve 15 N) toplam 300 metre kayma mesafesinde, 50 mm/sn kayma hızında ve kuru şartlarda yapıldı. Sürtünme katsayısı değerleri ile aşınma sonucundaki ağırlık kayıpları incelendi. Yapılan deneyler sonucunda hBN katkısının AZ91 alaşımı üzerinde sertlik değerinde çok daha yüksek değerleri...

Research paper thumbnail of Effect of Mechanical Alloying on Pack Boronizing

The powders containing B + SiC + KBF 4 were mechanically alloyed by planetary ball milling devices to 10 and 20 h, respectively. The samples were also boronized by the powder-(SiO 2-Na 2 O) mixture for 1023-1173 K temperature and 3, 6 and 12 h, respectively. At the end of the mechanical alloying process, it was determined that the powder particle sizes were in the nanometer scale. According to the microstructure analysis, a single-layer Fe 2 B structure was successfully obtained on the samples surfaces. It has been observed that the depth of the Fe 2 B boride layer, which has achieved high diffusivity by creating many defects in the form of nanometer-sized crystal particles, increased with repeated fracture and cold welding of the powder particles with increasing mechanical alloying times. By calculating the activation energies of the powders, their relations with the mechanically unalloyed samples were compared and empirical formulas that could be used for similar experimental conditions were produced.
