Insight into the mechanism of laminar plasma jet (LPJ) surface hardening is critical for the controllable preparation of ideal hardened layer to improve the wear and fatigue resistance of U75V Deping YU Professor (Full) Professor Sichuan Insight into the mechanism of laminar plasma jet (LPJ) surface hardening is critical for the controllable preparation of ideal hardened layer to improve the wear and fatigue resistance of U75V

Determining the heat flux distribution of laminar plasma

Mar 01, 2018 · Plasma surface hardening experiments on U75V steel with different axial distance from the torch exit were carried out. The sizes of the hardened layer were measured and used in the numerical simulation of the plasma surface hardening process to Effects of thermal plasma surface hardening on wear and Aug 30, 2017 · Wear tests of the rail steel treated by thermal plasma jet and untreated one were carried out on a block-on-ring wear test machine. Their corresponding wear and damage properties were contrasted. Results indicate that the microstructure of the heat-affected zone of the rail steel treated by thermal plasma surface hardening was transformed.

Laminar plasma jet surface hardening of the U75V rail

Insight into the mechanism of laminar plasma jet (LPJ) surface hardening is critical for the controllable preparation of ideal hardened layer to improve the wear and fatigue resistance of U75V Laminar plasma jet surface hardening of the U75V rail Insight into the mechanism of laminar plasma jet (LPJ) surface hardening is critical for the controllable preparation of ideal hardened layer to improve the wear and fatigue resistance of U75V rail steel. To reveal the surface hardening mechanism, a series of surface hardening experiments on the U75V rail steel surface were performed under different working parameters using a self-designed laminar plasma

Laminar plasma jet surface hardening of the U75V rail

Jul 25, 2020 · In this paper, to reveal the mechanism of the LPJ surface hardening of the U75V rail steel, surface hardening experiments have been carried out by a self-designed laminar plasma generator on U75V steel. By changing the arc current, the scanning velocity and the anode nozzle diameter of the laminar plasma generator, the ways for adjusting the geometrical dimensions of the
