Microbial fouling of heat exchangers causes serious issues including increased fuel consumption, flow resistance, and maintenance cost expenditure. Composite Ni‐P‐nanoTiO 2 coatings were prepared for inhibiting and mitigating the heat exchanger microbial fouling deposition. The surface energy components and wall adhesion work of microbial fouling medium had a significant effect on the microbial fouling deposition process. Compared with carbon steel coupons, the microbial fouling deposition on Ni‐P‐nanoTiO 2 coatings was reduced by about 90 % and the wall adhesion work and microbial fouling deposition rate of these coatings were less. The Ni‐P‐nanoTiO 2 coatings might not only be advantageous for controlling the initial microbial adhesion, but also effective for reducing the fouling deposition rate.
