Control of Wear of Magnetic Media with Sputtered i-Carbon Overcoats

这个项目解决了表面材料的磨损保护性质 存储在计算机系统中使用的硬磁盘上。 信息通过一个内置的读/写磁线圈存储在磁盘上 变成一个滑动器，滑动器骑在旋转磁盘旁边的薄空气膜上。 更高的信息密度需要更小的分离距离。 减小距离会增加接触和磨损的可能性。 这项研究评估了非晶碳的磨损性能， 溅射在镀覆的镍-钴或溅射的钴-铬上。 的 研究了摩擦磨损机理，分析了裂纹在磁场作用下的扩展规律， 膜/涂层界面进行了分析。

This project addresses the wear protective nature of a surface material deposited on a rigid magnetic disk used in computer systems. Information is stored on the disk by a read/write magnetic coil built into a slider which rides on a thin air film next to the rotating disk. Higher density of information requires smaller separation distance. Decreasing the distance increases the likelihood of contact and wear. This research assesses the wear properties of amorphous carbon which is sputtered on plated nickel-cobalt or sputtered cobalt-chrome. The mechanism of wear is studied and crack propagation at the magnetic film/overcoat interface is analyzed.
