摘要：

To　solve　the　difficulty　that　the　mixing　proportioning　of　various　powders　should　be　changed　continuously　to　satisfy　the　requirement　of　FGM(and　functional　part)　whose　components/properties　should　be　changed　continually　fabricated　by　laser　forming　processes,　the　four　channels　linkage　powder　feeding　system　was　designed　and　manufactured,　and　the　value　of　powder　output　of　each　channel　can　be　changed　continually.　This　paper　elaborated　the　theory　of　the　mechanism　design　and　electric　control　of　powder　feeding　system.　By　which　the　relevant　tests　were　made　with　Fe313　alloy　powder,　the　experimental　results　show　that　the　value　of　powder　output　can　be　changed　with　linear　functions　having　the　different　slope　lines　over　time.　With　this　powder　feeding　system,　the　thickness　of　cladding　layer　changed　continuously　was　achieved　in　6　kW　CO2　laser　cladding　experiment　with　Ni25　alloy　powder.
