چکیده

Zusammenfassung HPPMS‐Werkzeugbeschichtungen: Spanbildung und Reibung In der vorliegenden Studie wurden drei verschiedene mittels HPPMS abgeschiedene Verschleißschutzschichten – CrAlN+Mo:S, CrAlON TiAlCrSiN mit einem speziellen Hobelversuchsaufbau untersucht. Dabei die Kontaktlänge zwischen Span Spanfläche, Spandicke Reibungskoeffizient beim Hobeln gleichzeitige gemessen. Anhand von Hochgeschwindigkeitsaufnahmen können Prozesskräfte analysiert werden. Der Einfluss Beschichtung auf Kontaktlänge, Reibungskoeffizienten sowie Schnittgeschwindigkeit bestimmt. Das CrAlON‐beschichtete Werkzeug zeigte im Vergleich zu den CrAlN+Mo:S‐ TiAlCrSiN‐beschichteten Werkzeugen bei allen untersuchten Schnittgeschwindigkeiten eine geringere Adhäsionsneigung gegenüber dem Stahlwerkstück. Dies verhindert adhäsiven Verschleiß reduziert Reibung, wodurch verringert wird. Außerdem das reduzierte Kontaktlänge. Eine verringerte gehen in Regel einer verringerten thermischen Werkzeugbelastung einher verbessern somit Schnittleistung.

Low Friction CrNMPP/TiNDCMS Multilayer Coatings

Transition metal nitrides like CrN and TiN are widely used in automotive applications due to their high hardness and wear resistance. Recently, we showed that a multilayer architecture of CrN and TiN, deposited using the hybrid-high power impulse magnetron sputtering (HIPIMS) and direct current magnetron sputtering (DCMS)-HIPIMS/DCMS deposition technique, results in coatings which indicate not ...

Determination of workpiece flow stress and friction at the chip–tool contact for high-speed cutting

This paper presents a methodology to determine simultaneously (a) the flow stress at high deformation rates and temperatures that are encountered in the cutting zone, and (b) the friction at the chip–tool interface. This information is necessary to simulate high-speed machining using FEM based programs. A flow stress model based on process dependent parameters such as strain, strain-rate and te...

An analysis of strain in chip breaking using slip-line field theory with adhesion friction at chip/tool interface

A slip-line field model for orthogonal cutting with step-type chip breaker assuming adhesion friction at chip/tool interface is developed using Kudo’s basic slip-line field. An alternative method is suggested for estimation of breaking strain in the chip. The model proposed predicts that with decrease in distance of chip breaker from the cutting edge of the tool, the breaking strain and shear s...

Self-lubricating, low-friction, wear-resistant Al-based quasicrystalline coatings

After gas atomization, a quasicrystalline powder based on aluminium was used to prepare a thick coating by high-velocity oxygen-fuel flame torch spraying. This layer was deposited on top of a bond-coat layer on a steel plate. A post-spraying annealing treatment turned the two layers to their stable state, a γ-brass crystal and an icosahedral quasicrystal, respectively. The projection parameters...
