Their impact does not manifest as sudden failures, but rather as a gradual degradation of performance, which can lead to valve sticking, reduced efficiency of control components, and unplanned equipment downtime. The formation of varnish is associated with complex mechanisms of chemical and physical lubricant degradation, while conventional oil analysis parameters often fail to detect the early stages of this phenomenon. This paper discusses the mechanisms of varnish formation, the limitations of routine oil analysis, and modern diagnostic approaches for monitoring varnish potential, with an emphasis on preventive management of lubrication systems</dc:description><dc:description xml:lang="sl">Lakaste obloge (angl. varnish) predstavljajo enega ključnih, a pogosto spregledanih vzrokov za zmanjšano zanesljivost sodobnih hidravličnih in mazalnih sistemov. Njihova problematika se ne kaže v nenadnih okvarah, temveč v postopnem poslabševanju delovanja, ki lahko vodi v zatikanje ventilov, zmanjšano učinkovitost regulacijskih elementov in nepredvidene izpade opreme. Nastanek lakastih oblog je povezan s kompleksnimi mehanizmi kemijske in fizikalne degradacije maziva, pri čemer klasični para- metri analize olja pogosto ne zaznajo zgodnjih faz tega pojava. Prispevek obravnava mehanizme nastajanja lakastih oblog, omejitve rutinske analize olja ter sodobne diagnostične pristope za spremljanje potenciala nastanka laka s poudarkom na preventivnem upravljanju mazalnih sistemov</dc:description><edm:type>TEXT</edm:type><dc:type xml:lang="sl">znanstveno časopisje</dc:type><dc:type xml:lang="en">journals</dc:type><dc:type rdf:resource="http://www.wikidata.org/entity/Q361785" /></edm:ProvidedCHO><ore:Aggregation rdf:about="http://www.dlib.si/?URN=URN:NBN:SI:doc-FV30CBTF"><edm:aggregatedCHO rdf:resource="URN:NBN:SI:doc-FV30CBTF" /><edm:isShownBy rdf:resource="http://www.dlib.si/stream/URN:NBN:SI:doc-FV30CBTF/438ebef3-05ff-4629-ab05-cc7a70c088b2/PDF" /><edm:rights rdf:resource="http://rightsstatements.org/vocab/InC/1.0/" /><edm:provider>Slovenian National E-content Aggregator</edm:provider><edm:intermediateProvider xml:lang="en">National and University Library of Slovenia</edm:intermediateProvider><edm:dataProvider xml:lang="sl">Univerza v Ljubljani, Fakulteta za strojništvo</edm:dataProvider><edm:object rdf:resource="http://www.dlib.si/streamdb/URN:NBN:SI:doc-FV30CBTF/maxi/edm" /><edm:isShownAt rdf:resource="http://www.dlib.si/details/URN:NBN:SI:doc-FV30CBTF" /></ore:Aggregation></rdf:RDF>
