Mr.Santosh,
From what I read in some literatures the density of plasma coatings would be lower than the theoretical density of the same but compact material, where it can varies within 85 to 93%. Other reference also states that the Air Plasma Coating is usually in the range of 1-7% of porosity.
In my opinion, the HVOF may suit your needs as states in one literature the porosity of HVOF sprayed coatings is lower than 1%.
But certainly, the method depends on type of material you're spraying.
Cheers,
