 note = {In recent years, coating processes based on the impact of high-velocity solid particles such as
cold spraying and aerosol deposition have been developed and attracting much industrial
attention. A novel coating process called ‘warm spraying’ has been developed, in which
coatings are formed by the high-velocity impact of solid powder particles heated to appropriate
temperatures below the melting point of the powder material. The advantages of such process
are as follows: (1) the critical velocity needed to form a coating can be significantly lowered
by heating, (2) the degradation of feedstock powder such as oxidation can be significantly
controlled compared with conventional thermal spraying where powder is molten, and
(3) various coating structures can be realized from porous to dense ones by controlling the
temperature and velocity of the particles. The principles and characteristics of this new process
are discussed in light of other existing spray processes such as high-velocity oxy-fuel spraying
and cold spraying. The gas dynamics of particle heating and acceleration by the spraying
apparatus as well as the high-velocity impact phenomena of powder particles are discussed in
detail. Several examples of depositing heat sensitive materials such as titanium, metallic glass,
WC–Co cermet and polymers are described with potential industrial applications.},
