Table 3

Nanoindentation hardness and young modulus of the Ni-MMT (0.5%) nanocomposite films electrodeposited at various pHs (1.6, 2.5, 3.0).

Ni-MMT coatings pHs	Young modulus; (GPa ± SD, 𝑛=25)	Nanoindentation hardness; (GPa ± SD, 𝑛=25)
pH 1.6	147 ± 50	4.1 ± 1.5
pH 2.5	174 ± 52	3.3 ± 1.2
pH 3.0	234 ± 57	5.3 ± 1.6
