</p> <p> （1）熔覆速度快，出產(chǎn)率較高。 </p> <p> <br /> </p> <p> （2）熔深可控，稀釋率低。 </p> <p> <br /> </p> <p> 稀釋率首要指堆焊層與基體的堆疊交融處，其作用是操控堆焊的結(jié)合強度。如稀釋率過小則強度低（又冶金結(jié)合轉(zhuǎn)變?yōu)闄C械結(jié)合辦法）如稀釋率大則會影響堆焊層資料的功用和構(gòu)成堆焊層縮短應(yīng)力大，呈現(xiàn)開裂現(xiàn)象。一般操控在5%-10%左右。稀釋率如下圖： </p> <p> <br /> </p> <p> （3）堆焊面平整光滑，致密度高，可完畢0.5-5mm的堆焊面一次完畢。 </p> <p> <br /> </p> <p> （4）工藝安穩(wěn)性好，噴焊層質(zhì)量高，可長時間接連取得安穩(wěn)的堆焊層，且堆焊面無氣孔、沙眼等堆焊質(zhì)量問題。 </p> <p> <br /> </p> <p> （5）合金粉末制備簡練，運用資料規(guī)劃廣，可選用鈷基、鎳基、鐵基、銅基等粉末型焊材，且能夠依據(jù)工況直接配方。 </p> <p> <br /> </p> <p> （6）可依據(jù)需求裝備專機、機器人等，易于完畢主動化，減輕勞動強度。 </p> <p> <br /> </p> <p> （7）粉末運用率高，運用率可抵達75%以上。 </p> <p> <br />
