Simulation of laser zone texturing of Ni-P disk substrates by PLIC method

PLIC 방법을 사용한 Ni-P 디스크의 레이저 존 텍스처링 모사

Laser zone texture technology is widely used to enhance the tribological performance of high areal density media. This work investigates the transient process of melting and microscale surface deformation upon pulsed laser heating of Ni-P hard disk substrates by PLIC(Piecewise Linear Interface Calculation) method. The present results are compared with both the experimental and the Donor-Acceptor method results. It is found that the results from PLIC method are better than those of Donor-Acceptor method and they are in good agreements with the experimental results.
