Processing Window and Microstructure of NiCoCrAlY Coating Deposited on Cast Iron Using Multilayer Laser Cladding

open access: yesJournal of Spectroscopy, Volume 2019, Issue 1, 2019., 2019
Cast iron is an iron‐carbon alloy widely used in mechanical engineering. Nickel‐base or cobalt‐base alloy coatings prepared by laser cladding can improve the surface properties of cast iron, thereby increasing the service life of the components; however, due to the poor weldability and high carbon content of cast iron, the use of laser cladding to ...

Timing by rhythms: Daily clocks and developmental rulers

open access: yesDevelopment, Growth &Differentiation, Volume 58, Issue 1, Page 43-58, January 2016., 2016
We compare and contrast two biological "clocks". The circadian clock is used by organisms to regulate their behaviour in time with the 24 hour daily planetary cycle, whereas the segmentation clock appears to be an oscillatory ruler that is used briefly during development to subdivide the body axis into morphological segments.

Study on the spur involute gear meshing with planar enveloping hourglass worm based on local conjugate

open access: yes, 2017
In this paper, a novel multitooth point contact hourglass worm drive is proposed, which is composed of a planar enveloping hourglass worm and a spur involute gear, and both of them can be hardened and precisely ground. This novel hourglass worm drive is
