This new method is based upon the surface remelting of ceramic rods by using laser radiation, and its versatility is demonstrated in the surface structuring of two different eutectic composites with potential application as bone substitutes. Firstly, directionally eutectic rods of wollastonite (W)–tricalcium phosphate (TCP) and magnesium oxide (MgO)–magnesium stabilized zirconia (MgSZ) were grown by the laser floating zone technique. In the case of W-TCP eutectics, materials with crystalline, glass–ceramic, or vitreous microstructure could be obtained as the growth rate was increased. In the other case, a material made up of magnesium oxide and magnesium stabilized zirconia phases arranged in fibrillar or lamellar geometry was obtained. At higher solidification rates, the rupture of the growth front gave rise to the organization of the phases in the form of colonies or cells. The laser zone remelting technique was used to remove defects and to refine the microstructure of the directionally solidified eutectic surfaces as well as to cover MgO–MgSZ rods with W–TCP glass in the eutectic composition. The study provides a promising technique that can tailor the surface properties and functionality of bone repair materials. The products’ properties and challenges in preparation procedures are discussed. 000120145 536__ $$9info:eu-repo/grantAgreement/ES/DGA/T02-20R 000120145 540__ $$9info:eu-repo/semantics/openAccess$$aby$$uhttp://creativecommons.org/licenses/by/3.0/es/ 000120145 590__ $$a2.7$$b2022 000120145 592__ $$a0.492$$b2022 000120145 591__ $$aPHYSICS, APPLIED$$b78 / 160 = 0.488$$c2022$$dQ2$$eT2 000120145 591__ $$aENGINEERING, MULTIDISCIPLINARY$$b42 / 90 = 0.467$$c2022$$dQ2$$eT2 000120145 591__ $$aCHEMISTRY, MULTIDISCIPLINARY$$b100 / 178 = 0.562$$c2022$$dQ3$$eT2 000120145 591__ $$aMATERIALS SCIENCE, MULTIDISCIPLINARY$$b208 / 343 = 0.606$$c2022$$dQ3$$eT2 000120145 593__ $$aFluid Flow and Transfer Processes$$c2022$$dQ2 000120145 593__ $$aMaterials Science (miscellaneous)$$c2022$$dQ2 000120145 593__ $$aEngineering (miscellaneous)$$c2022$$dQ2 000120145 593__ $$aInstrumentation$$c2022$$dQ2 000120145 593__ $$aProcess Chemistry and Technology$$c2022$$dQ3 000120145 593__ $$aComputer Science Applications$$c2022$$dQ3 000120145 594__ $$a4.5$$b2022 000120145 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/publishedVersion 000120145 700__ $$aSola, Daniel 000120145 700__ $$0(orcid)0000-0003-2242-6822$$aPeña, Jose I.$$uUniversidad de Zaragoza 000120145 7102_ $$15001$$2065$$aUniversidad de Zaragoza$$bDpto.
