  The study of heavy-flavour (charm and beauty) production is important to
understand the properties of the Quark-Gluon Plasma (QGP) formed in
ultra-relativistic heavy-ion collisions, since heavy quarks are produced in the
initial stages of the collisions and subsequently interact with the medium
throughout its evolution. In the QGP, strange quarks are expected to be
abundantly produced and may recombine with charm quarks leading to an
enhancement of the nuclear modification factor ($R_{\rm AA}$) of ${\rm D}_{\rm
s}^{+}$ mesons compared to that of other charmed meson states at low and
intermediate $p_{\rm T}$. The measurement of elliptic flow ($v_{2}$) of ${\rm
D}_{\rm s}^{+}$ mesons is useful to determine the degree of thermalisation of
charm quarks in the collective expansion of the QGP. In addition, charm quarks
could recombine with light di-quark states in the medium, which would lead to
an enhancement of the $\Lambda_{\rm c}^{+}/{\rm D}^{0}$ baryon-to-meson ratio
as compared to that in pp collisions. Precise measurements of these particle
species in Pb-Pb collisions, therefore, give a deeper insight into the
hadronisation mechanisms that heavy quarks undergo in the strongly-interacting
medium. In this contribution, the latest results measured with ALICE for ${\rm
D}_{\rm s}^{+}$-meson and $\Lambda_{\rm c}^{+}$-baryon production in Pb-Pb
collisions at $\sqrt{s_{\rm NN}}=5.02$ TeV, using data from Run 2 of the LHC
are discussed.
