: Hot-dip galvanization is the most widely used method for the protection of steel against corrosion. The strategy of introducing hydrophobic nature to the hot-dip zinc coatings along with the corrosion resistance characteristics can enhance the protective efficacy and life time of the coatings. The effective enhancement in corrosion resistance and hydrophobic characteristics of hot-dip zinc coating can be achieved by incorporating metal oxide based composite into the coating matrix. In this contest, the present work explores the effect of introducing TiO 2 –Al 2 O 3 composite into hot-dip zinc coating for improving the hydrophobic and corrosion resistant characteristics of the coatings. The structural modification of the inner alloy layers of the hot-dip coating by using 0.2 wt.% of TiO 2 -Al 2 O 3 composite improves the hydrophobicity and corrosion resistance of the coating. Surface surface hydrophobicity and electrochemical performance of the composite coatings studied by using various instrumental analyses confirm the enhancement in coating characteristics due to the incorporation of TiO 2 -Al 2 O 3 composite into the zinc matrix. The composite zinc coating incorporated with optimized TiO 2 -Al 2 O 3 exhibits enhanced hydrophobicity with a water contact angle of 101.32° than the pure zinc coatings. The high E corr (-1267.17 mV) and low i corr (475.57 μA/cm 2 ) values of the composite coating as compared to the conventional zinc coating implies the improvement in corrosion resistance.

: Plasma-facing materials (PFMs) must be able to withstand conditions that are more extreme than anything naturally met on the face of the earth. Under the high particle and heat fluxes experienced in fusion plasma situations, cracking, surface roughening, blistering, hole formation, and melting have all been observed on tungsten PFMs. Degradation to PFMs in this way can lead to decreased performance in fusion reactors. Continued research and development of materials with properties that improve performance and minimise material degradation of the PFM is critical. This study compares diamond-like carbon (DLC) coatings and tungsten-doped DLC (W-DLC) coatings on pure polycrystalline tungsten substrates that have been exposed to hydrogen plasma. DLC coatings were prepared by plasma-assisted chemical vapour deposition (PECVD) with methane gas as the carbon source, in an RF plasma chamber. W-DLC coatings were prepared layer-by-layer via argon ion sputtering for the deposition of a tungsten layer between DLC layers. We present the results of coating of varying thickness that were prepared by altering the RF power, gas pressure and deposition time. The samples were exposed to a hydrogen plasma for a total of 120 hours. Changes in coating elemental composition and topography after exposure were observed by Auger and scanning electron spectromicroscopies. The thickness of each coating can be optimised to minimise degradation to tungsten PFMs, thereby improving the performance of fusion reactors.
