鈍化的機(jī)理可用薄膜理論來(lái)解釋，即認(rèn)為鈍化是由于金屬與氧化性質(zhì)作用，作用時(shí)在金屬表面生成一種非常薄的、致密的、覆蓋性能良好的、牢固地吸附在金屬表面上的鈍化膜。這層膜成**相存在，通常是氧化金屬的化合物。它起著把金屬與腐蝕介質(zhì)完全隔開(kāi)的作用，臺(tái)州表面處理設(shè)備便宜，防止金屬與腐蝕介質(zhì)接觸，從而使金屬基本停止溶解形成鈍態(tài)達(dá)到防腐蝕的作用。 </p> <p> 鈍化的優(yōu)點(diǎn)： </p> <p> 1、與傳統(tǒng)的物理封閉法相比，鈍化處理后具有不增加工件厚度和改變顏色的特點(diǎn)、提高了產(chǎn)品的精密度和附加值，臺(tái)州表面處理設(shè)備便宜，使操作更方便 </p> <p> 2、由于鈍化的過(guò)程屬于無(wú)反應(yīng)狀態(tài)進(jìn)行，鈍化劑可反復(fù)添加使用，因此壽命更長(zhǎng)、成本更經(jīng)濟(jì)； </p> <p> 3、鈍化促使金屬表面形成的氧分子結(jié)構(gòu)鈍化膜、膜層致密、性能穩(wěn)定，并且在空氣中同時(shí)具有自行修復(fù)作用，臺(tái)州表面處理設(shè)備便宜，因此與傳統(tǒng)的涂防銹油的方法相比，鈍化形成的鈍化膜更穩(wěn)定、更具耐蝕性。原始人類已具有愛(ài)美意識(shí)，在舊石器時(shí)代晚期，他們就利用礦石染料對(duì)個(gè)人自?shī)市∥锲愤M(jìn)行彩繪涂裝。臺(tái)州表面處理設(shè)備便宜</p><div

鍍層金屬或其他不溶性材料做陽(yáng)極，待鍍的工件做陰極，鍍層金屬的陽(yáng)離子在待鍍工件表面被還原形成鍍層。為排除其它陽(yáng)離子的干擾，且使鍍層均勻、牢固，需用含鍍層金屬陽(yáng)離子的溶液做電鍍液，以保持鍍層金屬陽(yáng)離子的濃度不變。電鍍的目的是在基材上鍍上金屬鍍層，改變基材表面性質(zhì)或尺寸。電鍍能增強(qiáng)金屬的抗腐蝕性(鍍層金屬多采用耐腐蝕的金屬)、增加硬度、防止磨耗、提高導(dǎo)電性、潤(rùn)滑性、耐熱性、和表面美觀。海曙區(qū)表面處理設(shè)備烘道但噴丸對(duì)薄板工件的處理，容易使工件變形，且鋼丸打擊到工件表面（無(wú)論拋丸或噴丸）使金屬基材產(chǎn)生變形。</p>

狹義的有色金屬又稱非鐵金屬，是鐵、錳、鉻以外的所有金屬的統(tǒng)稱。廣義的有色金屬還包括有色合金。有色合金是以一種有色金屬為基體(通常大于50%)，加入一種或幾種其他元素而構(gòu)成的合金。 </p> <p> <br /> </p> <p> 中國(guó)在1958年,將鐵、鉻、錳列入黑色金屬，并將鐵、鉻、錳以外的64種金屬列入有色金屬。這64種有色金屬包括：鋁、鎂、鉀、鈉、鈣、鍶、鋇、銅、鉛、鋅、錫、鈷、鎳、銻、汞、鎘、鉍、金、銀、鉑、釕、銠、鈀、鋨、銥、鈹、鋰、銣、銫、鈦、鋯、鉿、釩、鈮、鉭、鎢、鉬、鎵、銦、鉈、鍺、錸、鑭、鈰、鐠、釹、釤、銪、釓、鋱、鏑、鈥、鉺、銩、鐿、镥、鈧、釔、硅、硼、硒、碲、砷、釷。 </p><p> 采用堿性氧化法或酸性氧化法；使金屬表面形成一層氧化膜，以防止金屬表面被腐蝕，此處理過(guò)程稱為“發(fā)藍(lán)”。黑色金屬表面經(jīng)“發(fā)藍(lán)”處理后所形成的氧化膜，其外層主要是四氧化三鐵，內(nèi)層為氧化亞鐵。 </p> <p> <br /> </p> <p> <br /> </p> <p> <br /> </p> <p> 發(fā)藍(lán)（發(fā)黑）的操作流程： </p> <p> <br /> </p> <p> 工件裝夾→去油→清洗→酸洗→清洗→氧化→清洗→皂化→熱水煮洗→檢查。 </p> <p> <br /> </p> <p> 所謂皂化，是用肥皂水溶液在一定溫度下浸泡工件。目的是形成一層硬脂酸鐵薄膜，以提高工件的抗腐蝕能力。 </p> <p> 金屬表面著色，顧名思義就是給金屬表面“涂”上顏色，改變其單一的、冰冷的金屬色澤，代之以五顏六色，滿足不同行業(yè)的不同需求。 </p> <p> <br /> </p> <p> 給金屬著色后一般都增加了防腐能力，有的還增加了抗磨能力。但表面彩色技術(shù)主要的應(yīng)用還在裝飾領(lǐng)域，即用來(lái)美化生活，美化社會(huì)。由于四氧化三鐵和三氧化二鐵沒(méi)有塑性，破碎后剝離，而油膜與其材一同變形。</p><div style="width:100%;text-align: center;"><img style="max-width:
