Endüstriyel uygulamalarda kullanılan manyetik malzemelerdeki çatlakların fiziksel özelliklerinin belirlenmesi için bir manyetik tahribatsız test sistemi geliştirilmiştir. Araştırılan örnekler frekansı f=1000Hz ve akım değeri I=0.8A olan AC akımla manyetize edilmiştir. Örneklerin çatlak bölgesinin yüzeyi üç boyutta taranmıştır. Tarama esnasında yüzey manyetik kaçak akı sinyalleri Hall etkili algılayıcıyla toplanmıştır. Toplanan veriler çatlağın fiziksel özelliklerinin belirlenmesi için analiz edilmiştir. Bu makalede çatlakların fiziksel özellikleri hakkındaki bulgular ayrıntılı olarak bahsedilecektir.

INSPECTION OF CRACKS ON MAGNETIC MATERIALS

Öz

A magnetic non-destructive testing system was constructed for the inspection of cracks on magnetic materials for industrial applications. Investigated samples were magnetized by an ac current of f=1000Hz and I=0.8A. The surface of the samples were scanned for three dimensions. During the scanning process, the signal of surface magnetic leakege flux was collected by using a Hall effect sensor. The collected data was analized to obtain feature of the cracks on the sample. In this paper, findings about feature of the cracks will be presented.
