The effect of the sputtered target composition on the deposition rate of coatings formed by radio frequency magnetron sputtering (RFMS) is investigated. Strontium substitution in the sputtered β-tricalcium phosphate (β-TCP) target composition increases the coating deposition rate, whereas magnesium substitution decreases the coating deposition rate. Computer modelling shows that both the unit cell volume and bond lengths increase when strontium is introduced into the crystal lattice, whereas the incorporation of magnesium leads to a decrease in these parameters. A correlation between the change in unit cell volume due to magnesium and strontium substitutions, and the coating deposition rate is also determined.
