We present a new type of atomic layer deposition (ALD) process for intermetallic thin films, where diethyl zinc (DEZ) serves as a coreactant. In our proof-of-concept study, FeCl 3 is used as the second precursor. The FeCl 3 + DEZ process yields in situ crystalline Fe 4 Zn 9 thin films, where the elemental purity and Fe/Zn ratio are confirmed by time-of-flight elastic recoil detection analysis (TOF-ERDA), Rutherford backscattering spectrometry (RBS), atomic absorption spectroscopy (AAS), and energy-dispersive X-ray spectroscopy (EDX) analyses. The film thickness is precisely controlled by the number of precursor supply cycles, as expected for an ALD process. The reaction mechanism is addressed by computational density functional theory (DFT) modeling. We moreover carry out preliminary tests with CuCl 2 and Ni(thd) 2 in combination with DEZ to confirm that these processes yield Cu–Zn and Ni–Zn thin films with DEZ as well. Thus, we envision an opening of a new ALD approach based on DEZ for intermetallic/metal alloy thin films.

“…9 In this regard, zinc plating is frequently used to protect iron and steel against corrosion. 10,11 It is well-known that a zinc alloy with iron-group elements (Zn−X), such as Fe and Ni, can achieve a significant improvement in the protection properties of zinc coating. 12−14 Among them, Zn−Ni alloys have been widely used.…”

A simple, low-cost, fluorine-free, and ecofriendly method was applied to prepare a novel superhydrophobic Zn−Fe alloy coating on the surface of carbon steel. First of all, the Zn−Fe coating was obtained in an alkaline glycerol non-cyanide Zn−Fe plating solution. Then tetradecanoic acid was grafted onto the Zn−Fe coating by a coordination reaction, leading to a superhydrophobic surface. The water contact angle was up to 166°and the sliding angle was 4°. The as-prepared superhydrophobic coating exhibited high performances, such as strong adhesion to the substrate, impact resistance, selfcleaning, antifouling, and anticorrosion. Importantly, until now, few reports focus on the use of a non-cyanide alkaline glycerol plating bath for electrodeposition, which is green, composition-stable, and corrosion-free for devices. In addition, the growth mechanism of the Echinopsis multiplex-like hierarchical micro/ nanostructure of the superhydrophobic surface was studied in detail.

“…Nevertheless, it should be noted that phase composition of alloys of Fe-Zn system, both electrodeposited [11][12][13] and obtained by annealing of hot-dip zinc coating on steel substrates [14][15][16], is quite thoroughly investigated in the range of high zinc concentrations as these alloys are employed as corrosion-resistant coatings. However, the other possible areas of application of electrodeposited Fe-Zn alloys mentioned above also require more thorough investigations of this system in the range of high iron concentrations.…”

Presence of -phase, Fe 75 Zn 25 , Fe 3 Zn 10 and -phase in electrodeposited Fe-Zn alloys is determined by the method of X-ray diffractometry. The phase proportion varies with the increase of zinc concentration in the sulphate electrolyte. Discovered formation of Fe 75 Zn 25 phase during co-deposition of iron and zinc can be the cause of creation of previously revealed irregular surface relief with anomalously high roughness. Revision of Fe 75 Zn 25 phase atomic composition is accomplished by the numerical method based on precise value of the crystal-lattice spacing and taking into account elastic strain caused by zinc atoms, which are dissolved in the -Fe crystal lattice. Методою рентґенівської дифрактометрії визначено наявність в електроосаджених стопах Fe-Zn -фази, Fe 75 Zn 25, Fe 3 Zn 10 та -фази. Співвідношення фаз змінюється з ростом концентрації цинку в сульфатному електроліті. Виявлене вперше формування фази Fe 75 Zn 25 при сумісному електроосадженні заліза та цинку може бути причиною утворення виявленого раніше нереґулярного рельєфу поверхні з аномально високою шерсткістю. Уточнення складу фази Fe 75 Zn 25 здійснено чисельною методою, виходячи з прецизійного значення періоду ґратниці та з урахуванням пружньої деформації, яку зумовлено атомами Цинку, розчиненими в ґратниці -Fe. Методом рентгеновской дифрактометрии установлено наличие в электроосаждённых сплавах Fe-Zn -фазы, Fe 75 Zn 25 , Fe 3 Zn 10 и -фазы. Соотношение фаз изменяется с ростом концентрации цинка в сульфатном электролите. Обнаруженное впервые формирование фазы Fe 75 Zn 25 при совместном электроосаждении железа и цинка может быть причиной образования выявленного ранее нерегулярного рельефа поверхности с аномально высокой шероховатостью. Уточнение состава фазы Fe 75 Zn 25 выполнено численным методом, исходя из прецизионного значения периода решётки и с учётом упругой деформации, которая обусловлена атомами цинка, растворёнными в решётке -Fe.
