This study describes the performance of nanoscale multilayer TiN/NbN coatings deposited on CoCrMo medical-grade alloys by utilising novel mixed high power impulse magnetron sputtering (HIPIMS) and direct current unbalanced (UBM) technique in an industrial size vacuum coater. Scanning electron microscopy analysis showed that these were extremely dense without any intercolumnar voids. The coating...

Abstract Slurry-based 3D printing allows ceramic green bodies to be fabricated at high packing densities. In contrast powder-based binder jetting, full densification of printed parts can achieved in a subsequent sintering step as fine particles dispersed suspension are cast and compacted. is thus expected overcome the application limits alternative metal casting terms unfavorable properties lik...

Films of a biodegradable PLA/PBSA blend and blend-composites containing 2wt% of C20A, C30B and MEE were prepared by solvent casting and spin coating. The films were incubated in vials containing Tris-HCl buffer with Proteinase K, and their weight losses were measured after enzymatic degradation. The surface morphology before and after degradation tests was studied by SEM and in situ AFM. The re...

We present systematic experiments of the rupture and dewetting of thin films of a nonvolatile polar liquid on partially wetting substrates due to a moving slot jet, which impinges at normal incidence. The relative motion was provided by a custom-built spin coater with a bidirectionally accessible axis of rotation that enabled us to measure film thickness profiles in situ as a function of substr...

LLE Review, Volume 94 67 Introduction Large substrates for precision optical applications require the accurate, uniform deposition of multilayer thin-film coatings. Typically, this results in the use of electron-beam evaporation in a “box-coater” configuration, utilizing either simple or planetary rotation of the substrates. Simple rotation of the substrate minimizes the size of the necessary c...
