This paper exhibits an outline of the piston rings operational characteristics and
consequently, of their main functional challenges. The basic geometrical shapes, materials …

摘要飞秒激光加工与普通激光加工相比熔化区更小, 热影响区几乎可忽略不计,
同时其加工引起的冲击波及裂纹在通常条件下几乎不可见, 因而被广泛应用于精密加工 …

The radial surface coating layer of compression piston rings is used to improve their wear
resistance during the internal combustion engine operation. However, at top dead centers …

The micro-texture of the CVD diamond coating has the function of holding wear debris, and
can reduce the friction coefficient of the cutting tool through graphitization to a certain extent …

We report on femtosecond laser ablation and surface micropatterning (texturing) of diamond-
like nanocomposite (DLN) films (aC: H: Si: O films), aimed to improve tribological properties …

The work is devoted to the deposition of Ti-and Cr-doped aC: H: SiO x coatings on WC-8Co
substrates using plasma-assisted chemical vapor deposition and magnetron sputtering …

Femtosecond laser ablation processing is applied for surface modification and
micropatterning of diamond-like nanocomposite (DLN) films (aC: H: Si: O films). Using a …

We study the formation of laser-induced periodic surface structures (LIPSS) on diamond-like
nanocomposite (DLN) aC: H: Si: O films and titanium-doped DLN films during femtosecond …

In this study, the single-and multiple-pulse laser-induced surface damage characteristics of
the Ge 8 As 23 S 69 chalcogenide film under the femtosecond laser irradiation were …

Laser surface micropatterning (texturing) of hard materials and coatings is an effective
technique to improve tribological systems. In the paper, we have investigated the laser …
