Synthesis of single-component metallic glasses by thermal spray of nanodroplets on amorphous substrates [PDF]

open access: yes, 2012
We show that single component metallic glasses can be synthesized by thermal spray coating of nanodroplets onto an amorphous substrate. We demonstrate this using molecular dynamics simulations of nanodroplets up to 30 nm that the spreading of the ...

Spray Cooling Heat Transfer above Leidenfrost Temperature [PDF]

open access: yesMetals, 2020
This study considers spray cooling starting at surface temperatures of about 1200 °C and finishing at the Leidenfrost temperature. Cooling is in the film boiling regime. The paper uses experimental techniques for the study of which spray parameters are necessary for good prediction of spray cooling intensity.
