<strong>一篇帶你掌握刀片涂層（PVD涂層)</strong> </p> <p style="text-indent:2em;"> pvd涂層是一種常見的涂層方式，在我們的日常生活中很多時候都可以見到不同種類的涂層方式，<strong>成都pvd涂層</strong>廠家中科海下面就給大家總結一下pvd涂層的一些常見知識。 </p> <p style="text-indent:2em;"> 刀具涂層技術通?？煞譃榛瘜W氣相沉積（CVD）和物理氣相沉積（PVD）兩大類。硬質合金涂層刀片有PVD涂層和CVD涂層，本篇主要討論這PVD涂層。 </p> <p style="text-indent:2em;"> 1、刀具涂層的意義 </p> <p style="text-indent:2em;"> 在塑膠模具、沖壓模具、壓鑄模具、各種刀具、各種零部件、易損件行業里需要進行涂層；通過涂層，可以增加工件的表面硬度、增加耐磨性、增加耐腐性、增加抗粘性、減少摩擦、延長產品的工作時間或使用壽命,從而提高生產率、降低生產成本、提高加工可靠性、提高質量、縮短交貨時間、減少對環境的影響并節約資源、提高企業競爭力。 </p> <p style="text-indent:2em;"> 涂層的優點 </p> <p style="text-indent:2em;"> 涂層可以改善高溫硬度（紅硬性），提高刀具的耐磨性?？娠@著地提高刀具壽命； </p> <p style="text-indent:2em;"> 涂層摩擦系數小，涂層與被加工材料磨擦系數小，切削熱大部分傳入工件和切屑，能減小切削阻力，排屑流暢，有利于提高產品表面質量和延長刀具壽命 </p> <p style="text-indent:2em;"> 許多涂層刀具可以在較多場合用于干切削，不要切削冷卻液能降低消耗從而降低產品的生產成本； </p> <p style="text-align:center;text-indent:2em;"> <img src="http://img.dlwjdh.com/upload/14389/230213/e8522cfd727fbf89e6836ab2d1a236cf.jpg" alt="成都pvd涂層" width="618" height="419" title="成都pvd涂層" align="" /> </p> <p style="text-indent:2em;"> 2、PVD涂層 </p> <p style="text-indent:2em;"> PVD 技術主要應用于整體硬質合金刀具表面處理。與 CVD 工藝相比，PVD 工藝溫度低（較低可低至 80℃），在 600℃以下時對刀具材料的抗彎強度基本無影響；薄膜內部應力狀態為壓應力，更適于對硬質合金精密復雜刀具的涂層；PVD 工藝對環境無不利影響。 </p> <p style="text-indent:2em;"> 主要應用領域 </p> <p style="text-indent:2em;"> PVD 涂層刀片主要適用于整體刀具（銑削、鉆頭），銑削，螺紋加工，切斷，切槽加工，不銹鋼和耐熱合金的車削加工。 </p> <p style="text-indent:2em;"> PVD涂層種類 </p> <p style="text-indent:2em;"> 由于單一涂層材料難以滿足提高刀具綜合機械性能的要求，因此涂層成分將趨于多元化、復合化；為滿足不同的切削加工要求，涂層成分將更為復雜、更具針對性；在復合涂層中，各單一成分涂層的厚度將越來越薄，并逐步趨于納米化；涂層工藝溫度將越來越低，刀具涂層工藝將向更合理的方向發展。 </p> <p style="text-indent:2em;"> PVD涂層的選擇推薦 </p> <p style="text-indent:2em;"> 1) 氮化鈦涂層（TiN） </p> <p style="text-indent:2em;"> TiN 是一種通用的涂層，可以提高刀具硬度并具有較高的氧化溫度。 </p> <p style="text-indent:2em;"> 用途：硬質合金切削工具，慢速加工工具（如低速車刀粒），耐磨零件，注塑模具。 </p> <p style="text-indent:2em;"> 2) 氮碳化鈦涂層（TiCN） </p> <p style="text-indent:2em;"> TiCN 涂層是在 TiN 的基礎上添加碳元素，以提高涂層的硬度和低的摩擦系數。 </p> <p style="text-indent:2em;"> 用途：硬質合金刀具，沖壓模具，成型模具。 </p> <p style="text-indent:2em;"> 3) 氮鋁鈦（TiAlN） </p> <p style="text-indent:2em;"> 氮鈦鋁 AlTiN 俗稱：中鋁（Al:Ti=50:50）、高鋁（Al:Ti=67：33）以上， TiAlN/AlTiN涂層在加工過程中形成的氧化鋁涂層可以有效提高加工工具的高溫加工壽命，AlTiN 涂層的抗高溫氧化比 TiAlN 要高 100 度左右。 </p> <p style="text-indent:2em;"> 用途：硬質合金工具（加工材料硬度低于 HRC45 時建議用 TiAlN,加工材料硬度高于 HRC45 時建議使用 AlTiN 涂層。），薄壁件沖壓模具(TiAlN)，壓鑄模具（AlTiN）。 </p> <p style="text-indent:2em;"> 4) 氮化鉻涂層（CrN） </p> <p style="text-indent:2em;"> CrN 涂層具有良好的抗粘結性，抗腐蝕性，耐磨性。 </p> <p style="text-indent:2em;"> 用途：加工鋁合金，紅銅的刀具，注塑模具，零件（特別是有潤滑油浸泡） </p> <p style="text-indent:2em;"> 5) CBC （DLC） </p> <p style="text-indent:2em;"> PLATIT CBC是TIN+TICN+DLC結構。具有摩擦系數較低，耐磨損，膜層應力小好等優點。 </p> <p style="text-indent:2em;"> 用途：潤滑涂層，成型模具，鋁合金等粘結性強材料沖壓模具。 </p> <p style="text-indent:2em;">
