This study investigates the in vitro biocompatibility, corrosion resistance, and adhesion strength of a gas abrasive-treated Ti6Al4V alloy, alongside microplasma-sprayed titanium tantalum coatings. Employing novel approach selecting microplasma spray parameters, this successfully engineers coatings with tailored porosity, roughness, over 20% porosity pore sizes up to 200 μm, aiming enhance bone in-growth implant integration. introduces an innovative methodology for quantifying surface...
This article presents a study of changes in the microstructure Hadfield steel depending on tensile deformation and cold rolling with strain/stress level. It has been established that change "σ-ε" curve (at ε = 5%) is accompanied by 1.5-times decrease strain-hardening coefficient. At 0 to 5%, structure contains dislocation loops, interweaving elongated dislocations, single-layer stacking faults. multilayer faults mechanical microtwins. > there an intense microtwinning no long dislocations The...
The paper presents new results of automated path planning for an industrial robot manipulator performing microplasma spraying coatings on substrates with complex surface shapes. Path and automatic generation the motion program are performed using data a preliminary 3D scanning by laser triangulation distance sensor installed same arm. working tool algorithm is based choice starting segment trace as geodetic line surface. An optimal spatial curve approximation sequence segments arcs has been...
Part II presents the results which show that HA coatings significantly enhance MSC proliferation by 13% compared to titanium alloy base, while also exhibit an 11% increase. Porosity inversely affects CP-Ti’s elasticity. Coatings with lower porosity demonstrate better corrosion resistance. promote osteogenic activity and angiogenesis, is crucial for implant integration.
Abstract This paper presents new results of studying the influence parameters microplasma spraying (MPS) Zr wire on structure coatings. The coating experiments were accomplished in a two level fractional factorial design. Individual particles sprayed and their splats substrate collected under various (amperage, distance, plasma gas flow rate rate) evaluated by Scanning Electron Microscopy (SEM) to establish effect particle size shape microstructure. characterized measurement sizes obtained...
The article presents new results of studying the causes material loss during microplasma spraying (MPS) and substantiates choice optimal parameters for efficient zirconium wire coatings on steel substrates obtaining with desired porosity up to 20.3% a titanium alloy. Optimum provide maximum utilization coefficient (MUC) - 95%, minimum losses when small parts: 47% onto substrate an average cross-sectional area 2 mm less than 1% diameter 8 mm. studies were carried out using multifactorial...
