he graphite-like structure of the ceramic particles enables them to fill in the roughness present in the metal, thereby preventing direct metal-on-metal contact.
An active chemical (friction modifier) utilizes the existing friction energy to ensure flowing i.e. non-abrasive – smoothing, annealing the friction and bearing points.
Test arrangement with two interlocking gear wheels.
Tooth edges with marked traces of wear.
LIQUI MOLY products stand for reliability, efficiency and for top quality – a performance promise which an independent institute, renowned in the best sense of the word, should put to the test: The Automobil-Prüftechnik-Landau GmbH (APL) tested Cera Tec.
What was tested
The APL experts determined the relative scuffing load capacity of lubrication oils. Between the edges of the teeth, rolling off and sliding occur at the same time. Due to unfavorable operating conditions the lubricant film can break down between the tooth edges. This leads to short-term local fusion and disintegration of the edges, so-called scuffing, which causes damage to the smooth surface of the teeth edges. Possible consequences: higher engine and transmission noise until failure of the gear wheels occurs.
On the vehicle distortion test bench the test oil was mixed with 6 per cent Cera Tec. With each test sequence the weight, and thereby the force level, on the sensitive transmission gear wheels was increased. The aim of the experiment is to reach the damage force level. This level is reached when the sum of all damage caused to the teeth of the gear wheels is more than 20 millimeters. The test is then ended. The reference oil came up to damage force level 4; the oil mixed with Cera Tec reached as far as level 9, hence to more than double the level. «Cera Tec markedly increases the power reserve, which confirms the anti-wear protection by the fine ceramic particles,» is how Dipl.-Ing. Peter Kunz, who supervised the test, summarizes the results. Kunz’s initial skepticism gave way: After the tests I was amazed. The product has made everything, and I really mean everything, better.»
Just the demand for APL’s expertise alone has been unusual. «LIQUI MOLY is the first company in the after-sales market that has been prepared to undergo voluntary tests», said Kunz. He is responsible for the testing of lubricants and fuels.
This is APL
Formed in 1989, APL is a neutral and independent, internationally renowned development service provider, working for a worldwide client base from the automobile, oil and additives industries. The company is specialized in the mechanics of engine and drive trains and their operating supplies. On nearly 145 state of the art engine and component test rigs, more than 700 employees apply the latest measurement technology
Cera Tec reduces the amount of friction and thereby the wear. This in turn benefits the engine, which is under less load. This can result in a lower susceptibility to repair and longer service life.
What is Cera Tec and how do I apply it?
Cera Tec is a suspension based on a microceramic solid lubricant and chemical active agents in mineral oil. This is how it is applied:
