“…CHA coatings were synthesized using many preparation methods including plasma spray, ion-beam sputtering, laser ablation, electrochemical deposition, pulsed-laser deposition, thermal dissociation under hydrothermal conditions, biomimetic processes, liquid immersion techniques, magnetron sputtering and sol-gel techniques [1,5,6,10,[18][19][20][21][22][23][24]. It is very important to choose a controllable method for the synthesis of CHA to ensure homogeneity, good mechanical properties and adherence of coatings.…”
