Abstract:
Objective To study anti-radiation behavior of plasma sprayed boron carbide coatings. Methods The anti-radiation capacity of 16Mn steel which was coated with 0.1 mm plasma sprayed boron carbide were studied. The irradiation beams were 6,10,15 MY X-ray and 6,9,12,15 MeV electron emitted by accelerator, X-ray emitted by 60Co machine,fast neutron, and X-ray emitted by kilovoltage X-ray ma-chine. Results Anti-radiation capacity of plasma sprayed boron carbide coatings was not found for X-ray beams emitted by accelerator and 60Co machine. For electron beams,the anti-radiation capacity were found. The deeper of location, the stronger was anti-radiation. However, the anti-radiation capacity was not good. For fast neutron,the anti-radiation capacity was good. For X-ray emitted by kilovoltage X-ray machine,the anti-radiation was good,and only 0.1 nun plasma sprayed boron carbide had 15% attenuation. Conclusions The plasma sprayed boron carbide coatings have the anti-radiation capacity for X-ray emitted by kilovoltage X-ray machine in medical field.
