C23C 16/453

passing the reaction gases through burners or torches, e.g. atmospheric pressure CVD (C23C16/513 takes precedence; for flame or plasma spraying of coating material in the molten state C23C4/00)

Introduced: January 2000

Title

Titles differ between systems:

IPC: passing the reaction gases through burners or torches, e.g. atmospheric pressure CVD

CPC: passing the reaction gases through burners or torches, e.g. atmospheric pressure CVD (C23C16/513 takes precedence; for flame or plasma spraying of coating material in the molten state C23C4/00)

Full Title

Full titles differ between systems:

IPC:

Chemical coating by decomposition of gaseous compounds, without leaving reaction products of surface material in the coating, i.e. chemical vapour deposition [CVD] processes > characterised by the method of coating > passing the reaction gases through burners or torches, e.g. atmospheric pressure CVD

CPC:

Chemical coating by decomposition of gaseous compounds, without leaving reaction products of surface material in the coating, i.e. chemical vapour deposition [CVD] processes (reactive sputtering or vacuum evaporation C23C14/00) > characterised by the method of coating (C23C16/04 takes precedence) > passing the reaction gases through burners or torches, e.g. atmospheric pressure CVD (C23C16/513 takes precedence; for flame or plasma spraying of coating material in the molten state C23C4/00)
