    • Decarburization during laser surface processing of steel 

      Maharjan, Niroj; Zhou, Wei; Zhou, Yu; Wu, Naien (2018)
      Unwanted removal of carbon from surface may occur during laser surface processing of steels despite the short interaction time and thermal cycle. However, no attention is paid in literature to investigate this phenomenon ...
    • Femtosecond laser cleaning for aerospace manufacturing and remanufacturing 

      Maharjan, Niroj; Zhou, Wei; Zhou, Yu; Guan, Yingchun (2017)
      Microsecond and nanosecond lasers have been studied in the past for laser cleaning applications, but femtosecond laser is rarely used for cleaning due to the greater possibility of ablation from the extremely high peak ...
    • Influence of operating parameters on morphology of laser hardened surfaces 

      Maharjan, Niroj; Zhou, Wei; Zhou, Yu; Wu, Naien (2018)
      Conventional heat treatment of a component is performed in a furnace whereby the component is continuously heated to a high temperature and quenched to get a hardened material. The furnace heating and tempering process ...
    • Surface ablation of 52100 bearing steel using femtosecond laser irradiation 

      Maharjan, Niroj; Zhou, Wei; Zhou, Yu (2018)
      Laser ablation is a rapid-material removal technique with potential application in remanufacturing of bearings to clean damaged surfaces. This study reports the ablation morphology and change in surface composition of 52100 ...
