Study of a polycrystalline Ni/Cr alloy V. Hydrogen-atom exposure

Structural and surface properties of NiCr thin films prepared by DC magnetron sputtering under variation of annealing conditions

“…XPS analysis results suggest that while Nimetal, Ni(OH) 2 , and small quantity of Cr-oxide existed in specimen surfaces before annealing, NiO and Ni 2 O 3 were formed after annealing in air ambient, and Ni-oxide was reduced and Croxide remained after annealing in H 2 ambient. The reason that Ni(OH) 2 appeared in H 2 ambient while Cr-OH composites did not be detected and which may be explained as the relatively unstable Cr-group hydroxides were removed quickly when hydrogen atomic fluid produces moisture and removes it in the surface layer [15]. For large grains formed after annealing treatment in H 2 ambient, Ni elements existed in a large quantity in surfaces as observed in AES analysis, suggesting Ni-group composites.…”

Annealing effect on the electrical properties and microstructure of embedded Ni–Cr thin film resistor

“…However, in fact the unstable Cr (OH) 3 cannot exist at high temperatures and near-surface region [21], so there might be the oxides of chromium which do not mentioned in the literature. The reason that Cr(OH) 3 did not appear on surface of thin film while Ni(OH) 2 appear might be explained that the unstable Cr(OH) 3 was removed rapidly during the exposure to H atoms through formation of water molecules [22,23]. It is found in Fig 5(E) that the Cr increased obviously with the temperature increasing, indicating that the easily oxidized chromium was moved.…”
