The increased demands for higher efficiency and environmentally friendly diesel engines have led to a continuous search new coating processing routes ceramic materials that can provide the required properties when applied on engine components such as pistons exhaust manifolds. Although successful in gas turbine applications, thermal barrier coatings (TBCs) produced by suspension plasma spraying (SPS) processes not been employed so far automotive industry. This work aims achieve better...
Abstract Demands for improved fuel efficiency and reduced CO 2 emissions of diesel engines have been the driving force car industry in past decades. One way to achieve this would be by using thermal spraying apply a insulation layer on parts engine’s combustion chamber. A candidate spray process give coatings with appropriate properties is suspension plasma (SPS). SPS, which uses liquid feedstock deposition finely structured columnar ceramic coatings, was investigated work application...
Commercially available LaFeO3 powder was processed using the spark plasma sintering (SPS) technique. The results of dielectric measurement showed high permittivity, but this strongly frequency-dependent and also accompanied by a loss tangent. chemical purity changes induced SPS process influenced stability parameters bulk compacts. A microstructure with homogeneous grain size certain porosity produced. microhardness sintered rather high, about 8.3 GPa. All are in reasonable agreement...
By applying the physical vapour deposition method, hollow ceramic microspheres were coated with titanium, and subsequently, they sintered using spark plasma sintering technique to create a porous material that is lightweight devoid of matrix. The process was carried out at temperatures ranging from 1050 1200 °C, holding time 2 min. samples subjected conventional thermal analyses (differential scanning calorimetry, thermogravimetry, dilatometry), oxidation resistance tests, diffusivity...
Magnesiummanganese (MgMn) based alloys with various chemical composition were processed by indirect extrusion at two dierent speeds.Alloying Mn and rare earth elements has signicant inuence on the microstructure texture of under investigation.This paper deals acoustic emission analysis deformation behavior extruded MgMn alloys.The measurements performed during uniaxial tension compression tests, obtained results are discussed respect to rare-earth behavior, particularly in terms activation...
This work is focused on the structural and physical properties of CePt2Al2, an intermetallic compound. At room temperature, modulated orthorhombic structure Cmme(a00)000, with q→= (0.481, 0, 0) has been determined by single-crystal X-ray diffraction supplemented dependence lattice parameters above temperature for which powder was used. The compound undergoes a transition to tetragonal temperature. exhibits 50 °C hysteresis creates domain in sample. magnetic behavior studied specific heat,...
This paper focuses on the analysis of deformation behaviour with respect to acoustic emission response and mechanical properties differently extruded magnesium Mg-Mn alloys. Six types alloys (with Al, Ca, Ce, Y, Nd additions) were processed by indirect extrusion two different speeds. Alloys addition Al selected presented in this manuscript due their prospective properties. Additions Ca had significant influence microstructure refinement texture alloy, whereas led absence tension-compression...
Thin yttria-stabilized zirconia (YSZ) coatings were deposited on stainless steel substrates from liquid feedstocks by plasma spray technology. The porosity of the coating has a substantial effect its thermal properties depending morphology and orientation pores. Properties four different YSZ layers (“cauliflower-like” dense) measured laser flash diffusivity method RT to 800 ºC. Different analytical models for conductivity applied compared purpose validation barrier (TBCs) prepared hybrid...
The CeT2X2 (T: transition element, X: p-element) intermetallics are intensively studied for their magnetic properties and exotic ground states.Determination of crystal structure is usually the basic characterisation further research, but this not case in CePt2Al2 selected homolog compounds, which structurally unstable at low temperatures.This structural instability influences then electronic plays key role.CePt2Al2 a new member family, therefore we focused on broad temperature interval 3...
