[Table] shows the types and characteristics of oxygen fuel spraying using gas as the heat source.
 | Flame spraying | Detonation flame spraying |
Wire flame | Rod flame | Powder flame | Detonation flame | High velocity flame | FARE GUN process |
 | Oxyacetylene, oxyhydrogen flame, oxypropane | Oxyacetylene | Oxyacetylene, oxyhydrogen flame, oxypropane | Explosion energy of oxyacetylene | Explosion energy of oxygen propane MAPP (C2H3) | Explosion energy of air MAPP (C2H3) |
 | Steel materials such as carbon steel and
stainless steel, non-ferrous
metals including nickel/
molybdenum
and their alloy metals | Oxides such as AL2O3, Cr2O3, ZrO3, and ZrSiO4 | Most of the metals, nylon and epoxy resin, oxides including AL2O3・TiO2 | Most of the metals, oxides including AL2O3 and Cr2O3, carbides including WC-Co and CrC, and cermet | Most of the metals, carbides including WC-Co and CrC-Ni-Cr, some of the oxides, and cermet | Most of the metals, carbides including WC-Co and CrC-Ni-Cr, some of the oxides, and cermet |
 | Wire | Rod | Powder | Powder | Powder | Packed powder |
 | Most of the metals;
glass, ceramics and two to three organic materials with some limitations | Most of the metals and graphite,
etc. | Most of the metals;
glass, ceramics and two to three organic materials with some limitations | Most of the metals | Most of the metals | Most of the metals |
 | Can be controlled under 200 ℃ |
 | 5-15% | 5-18% | 10-20% | No more than 3% | No more than 3% | No more than 3% |
 | Simple equipment allows for spraying materials on site. | Oxide thermal spray can be applied with gas flame. | Oxide
thermal spray can be applied.
Suitable for plastic spraying. | Dimensions and shapes of the substrates are limited.
High film density. |
Fuel is economical. Equipment is small.
Suitable for carbides.
High film density. | Suitable for spraying tiny areas.
Difficult to spray oxides.
High film density. |
