Study on Changes of Metal Chemical Composition by Abrasive Wear of Alfalfa Powder
The abrasive wear of 45 steel and HT200 iron which are usually used on agriculture machine was tested by alfalfa powder on a grinding abrasion testing machine. The chemical composition on both wear metal surface and original surface were analysed with energy dispersive spectroscopy (EDS). The results indicated that metal element contents on the metal wear surface were decreased, while the nonmetallic element contents were increased.
