doi:10.15541/jim20170519

Abstract

Abstract:

Nanobelt Ca_0.68Si₉Al₃(ON)₁₆ : Eu²⁺luminescence fibers for wear detection of disc cutter were prepared by a simple process electrospinning combined with gas-reduction method, and then characterized by FE-SEM, XRD, PL, and universal material testing machine. The obtained sample keeps fiber film state in micro and macroscopic level with a certain mechanical strength, temperature, waterproof and chemical stability. XRD patterns of the sample doped with Eu²⁺ 0.1 nitrided at 1500℃ for 4 h were crystallized well and assigned to Ca_0.68Si₉Al₃(ON)₁₆in JCPDF card. The fiber film can be effectively excited by blue light, showing a broad emission spectrum in the range from 400 to 700 nm. The luminescent fiber film can be practically assembled onto disc cutters for detection. The wear degree of each cutter can be real-timely monitored in the main control room, which reduces the artificial detection at high pressure and high risk geological section, the investment cost, and the occupational risk of operators.
