External grind-hardening forces modelling and experimentation [PDF]

open access: yes, 2013
Grind hardening process utilizes the heat generated in the grinding area for the surface heat treatment of the workpiece. The workpiece surface is heated above the austenitizing temperature by using large values of depth of cut and low workpiece feed ...

Surface hardening equipment [PDF]

open access: yesChemical and Petroleum Engineering, 2013
Use of a new device UDGZ-200 is considered for surface hardening. Its use increases the service life of body components, gear connections, crane wheels and rails, dies, etc., due to a marked reduction in machine and equipment down time. Its introduction does not require workshop modernization: it is capable of compensating for a lack of traditional ...

Constraining the parameter space of comet simulation experiments [PDF]

open access: yes, 2018
Our interpretation of the data returned by Rosetta and other cometary missions is based on the predictions of theoretical models and the results of laboratory experiments. For example, Kossacki et al. (2015) showed that 67P's surface hardness reported by
