The effects of milling speed and calcinations temperature towards La0.6Sr0.4CO0.2Fe0.8O3-δ-SDC carbonate (LSCF-SDC carbonate) composite cathodes were investigated. The preparation of samarium-doped ceria (SDC) carbonate was firstly done by milling the SDC nanopowder with carbonate using the high-energy ball milling (HEBM) in air at room temperature. The obtained SDC carbonate was then used to mill with composite powder of lanthanum strontium cobalt ferrite (LSCF) which is one of the promising materials for the cathode of solid oxide fuel cells (SOFC). The purpose of milling LSCF composite powder with SDC carbonate was to get new composite cathode for intermediate-to low-temperature solid oxide fuel cells (IT-TLSOFC). LSCF composite powder with SDC carbonate was milled using high-energy ball milling with milling speed of 150 rpm and 550 rpm and calcinations temperatures of 750°C, 800°C, 850°C and 900°C. Field emission scanning electron microscopy (FESEM) analysis revealed the presence of large particle resulting from the increasing of calcinations temperature. FESEM also shows the particle size decrease in size with the increasing of milling speed. Therefore, the speed of 550 rpm and temperature of 900°C were found to be the best milling speed and calcinations temperature in producing the composite cathode of LSCF-SDC carbonate.

Air plasma spray technique (APS) is widely used in the biomedical industry for the development of HA-based biocoatings. The present study focuses on the influence of powder homogenization treatment by high-energy ball milling (HEBM) in developing a novel hydroxyapatite-barium titanate (HA/BT) composite coating deposited by APS; in order to compare the impact of the milling process, powders were homogenized by mechanical stirring homogenization (MSH) too. For the two-homogenization process, three weight percent ratios were studied; 10%, 30%, and 50% w/w of BT in the HA matrix. The phase and crystallite size were analyzed by X-ray diffraction patterns (XRD); the BT-phase distribution in the coating was analyzed by backscattered electron image (BSE) with a scanning electron microscope (SEM); the energy-dispersive X-ray spectroscopy (EDS) analysis was used to determinate the Ca/P molar ratio of the coatings, the degree of adhesion (bonding strength) of coatings was determinate by pull-out test according to ASTM C633, and finally the nanomechanical properties was determinate by nanoindentation. In the results, the HEBM powder processing shows better efficiency in phase distribution, being the 30% (w/w) of BT in HA matrix that promotes the best bonding strength performance and failure type conduct (cohesive-type), on the other hand HEBM powder treatment promotes a slightly greater crystal phase stability and crystal shrank conduct against MSH; the HEBM promotes a better behavior in the nanomechanical properties of (i) adhesive strength, (ii) cohesive/adhesive failure-type, (iii) stiffness, (iv) elastic modulus, and (v) hardness properties.
