目前關于中空玻璃生產線磨損尚無統一的分類方法,大體可概括為兩類:一類是根據磨損結果對磨損表觀的描述,如點蝕磨損、膠合磨損、擦傷磨損等;另一類是根據摩擦機理,分磨粒磨損、粘著磨損、疲勞磨損、腐蝕磨損等。
At present, there is no unified classification method for the wear of insulating glass production line, which can be summarized into two categories: one is the description of wear appearance according to wear results, such as pitting wear, gluing wear, scratch wear, etc; The other is divided into abrasive wear, adhesive wear, fatigue wear, corrosion wear and so on according to the friction mechanism.
1.粘著磨損
1. Adhesive wear
在切向力的作用下,摩擦副表面的吸附膜和服污膜遭到破壞,使表面的輪廓峰在相互作用的各點處發生冷焊,由于相對運動,材料便從一個表面轉移到另一個表面,形成粘著磨損。在此過程中,有時材料也會再次附著回原表面,出現逆轉移,或脫離所粘附的表面而成為游離顆粒。載荷越大,表面溫度越高,粘著的現象也越嚴重,嚴重的粘著磨損會造成運動副咬死,粘著磨損是金屬摩擦副之間普遍的一種磨損形式。
Under the action of tangential force, the adsorption film and fouling film on the surface of friction pair are damaged, so that the contour peak of the surface is cold welded at each point of interaction. Due to relative movement, the material is transferred from one surface to another, forming adhesive wear. In this process, sometimes the material will adhere back to the original surface, reverse transfer, or separate from the adhered surface and become free particles. The greater the load is, the higher the surface temperature is, the more serious the adhesion phenomenon is. Serious adhesion wear will cause the moving pair to bite. Adhesion wear is a common form of wear between metal friction pairs.
2.磨粒磨損
2. Abrasive wear
中空玻璃生產線磨粒磨損從外部進入摩棕面間的游離硬質顆粒(如塵土或磨損造成的金屬微粒)或硬的輪廓峰尖,在較軟材料表面犁刨出很多溝紋而引起材料脫落的現象,稱為磨粒磨損。磨粒磨損與摩擦副材料的硬度和磨粒的硬度有關。有時選用較便宜的材料,定期更換易磨損的零件,更符合經濟原則。
Abrasive wear of insulating glass production line is the phenomenon that the free hard particles (such as dust or metal particles caused by wear) or hard contour peaks entering the friction brown surface from the outside, plough out many grooves on the surface of softer materials, resulting in material falling off, which is called abrasive wear. Abrasive wear is related to the hardness of friction pair materials and abrasive particles. Sometimes, it is more economical to choose cheaper materials and replace easily worn parts regularly.
3.疲勞磨損
3. Fatigue wear
在變接觸應力的作用下,如果該應力超過材料相應的接觸疲勞極限,就會在摩擦副表面或表面以下一定深度處形成疲勞裂紋,隨著裂紋的擴展及相互連接,金屬微粒便會從零件工作表面上脫落,導致表面出現麻點狀損傷現象.即形成疲勞磨損或稱疲勞點蝕。
Under the action of variable contact stress, if the stress exceeds the corresponding contact fatigue limit of the material, fatigue cracks will be formed on the surface of the friction pair or at a certain depth below the surface. With the expansion and interconnection of the cracks, metal particles will fall off from the working surface of the parts, resulting in pitting damage on the surface, that is, fatigue wear or fatigue pitting corrosion.
4.腐蝕磨損
4. Corrosion and wear
中空玻璃生產線腐蝕磨損摩擦過程中,金屬與周圍介質(如空氣中的酸、潤滑油等)發生化學或電化學反應而引起的表面損傷,稱為腐蝕磨損。其中氧化磨損為常見,這是金屬摩擦附在氧化性介質中工作時,接觸表面反復生成、磨去氧化膜的磨損現象,實際上是化學氧化和機械磨損兩種作用相繼進行的過程。氧化磨損的大小取決于氧化膜的連接強度和氧化速度。
The surface damage caused by chemical or electrochemical reaction between metal and surrounding medium (such as acid in air, lubricating oil, etc.) in the process of corrosive wear and friction of insulating glass production line is called corrosive wear. Oxidation wear is common, which is the wear phenomenon of repeatedly generating and grinding off the oxide film on the contact surface when the metal friction is attached to the oxidizing medium. In fact, it is a process of chemical oxidation and mechanical wear. The size of oxidation wear depends on the connection strength and oxidation rate of oxide film.
除了上述4種基本中空玻璃生產線磨損類型外,還有一些磨損現象可視為是基本磨損類型的派生或復合。前者如浸蝕磨損,后者如微動磨損。
In addition to the above four wear types of basic insulating glass production line, some wear phenomena can be regarded as derivation or combination of basic wear types. The former is erosion wear and the latter is fretting wear.
