Research of mechanical properties of a micro/nano rod material based on the shape of Nocadia

The mechanical properties of Nocadia before and after metallization are determined by nanoindentation technology. Nocaida is a land of rod-shaped bacteria with submicrometer in diameter and 3-10 mum in length. The elastic modulus of metallized Nocadia, Nocadia and resin is 14.16 GPa, 9.50 GPa and 5.72 GPa, respectively. The hardness is 0.60 GPa, 0.27 GPa and 0.30 GPa, respectively. There is a great improvement in elastic modulus and hardness compared with those of bare Nocadia. This is due to a powerful mechanical foundation supplied by the Ni-P metallization layer.
