Later, we use powder as the sputtering source, adopt the method of reactive sputtering target doped powder to "sputter" and successfully produce (with SnO2-based materials) thin film gas sensors.
Using the powder sputtering method, we have produced in succession thin film gas sensors components with good performance by means of ZnO, Fe2O3 and TiO2-based materials.
Fig.1 Chip structure a) The gas sensing film is limited to the inter-digital electrode area using SnO2/x%CeO2 as materials.

The results available in literature show that cold spray could be used to produce thick dense coatings of a wide range of materials, tantalum, copper, aluminum, zinc, nickel etc.[11,12].
Ability to deposit materials with different nature, high build rates and reduced operation cost and more adherent coating are attractive characteristics of this hybrid additive process.
It can be found that specific heat input is not enough for complete remelting of all materials at working parameters of 40 W and 10 mm/s laser spot travelling velocity.
