TL;DR: Considering all results of WE43, its application as osteosynthesis material for fracture repair is ineligible due to its heterogeneous and unpredictable degradation behaviour and its use as degradable implant material seems to be limited.

TL;DR: Eight cylinders coated with a magnesium-fluoride layer and implanted in the marrow cavities of both tibiae of 10 New Zealand White rabbits showed a slight decrease in volume in comparison to uncoated implants and the mechanical properties of the coated implants exhibited a reduction in strength after 3 months.

TL;DR: In this paper, the suitability of spray cooling was assessed by means of hardness measurements, residual stress conditions, distortion measurements and by metallographic examinations, based on the analyses currently carried out, it was possible to show that the two-phase spray cooling represents an alternative quenching method which produces comparable component properties.

TL;DR: In this article, the interchangeability of polymer solutions used during induction hardening with water-air spraying regarding compressive residual stresses was investigated. Butts et al. showed that the effect of different cooling parameters on the surface's residual stresses in the gearwheel's tooth flanks was analyzed by means of X-ray diffraction.

TL;DR: In this article, an additional tempering from the residual heat was performed during induction hardening of helical gearwheels made of 42CrMo4 heat-treating steel using a controlled quenching by means of spray cooling.
